/usr/bin/which is a 'csh' script.

It sources your ~/.cshrc file, and there was piece that failed when run
in a non-interactive mode.

I wrapped the offending code in a test for $prompt, and the problem went
away.

if ( ${?prompt} ) then
....
endif

other options suggested to track down the problem

You can start by comparing the 'which' executables on two machines, one
that behaves normally and the one that produces the 'No match' messages.
They'll probably match, but it's good to be thorough.

	sum /usr/bin/which

Since 'which' is a shell script (and a fairly short one at that), you
can easily debug it; try the command:

	csh -vx /usr/bin/which metastat


Run a truss command on the which command.
For example:

	# truss -fea -o /tmp/which.out /usr/bin/which metastat

Patch 112837-12 fixes this problem. This requires a support contract for access

Our client is a ".gov.uk" client and so do not want any of their IP
configs to leave their datacentre. I don't have access to a Sun server
and/or explorer.
But I do remember that explorer has a defaults config file.

In other words can you do

# /opt/SUNWexplo/bin/explorer -w defaults,nonet

Message-ID: <468B1619.7070708@iinet.net.au>

Greetings,

It seems that 106122-11 is the latest OPB for the Ultra Enterprise 450.

    OBP 3.30.0 2003/11/11 10:41   POST 6.1.0 2003/11/11 10:27

As for the prtdiag reporting NO DISK in upper slots, let me quote from
Richard Butler's e-mail:

"I was told (talking to a Sun tech) that the problem is that the base
4-disk backplane is not full (Disk 3).  It appears the OBP then assumes
all the higher numbers are empty (I would call this a bug!).  The hardware
manual does however say "Each disk drive should be installed in the
lowest-numbered drive slot available.  Fill drive bays from the bottom
of the disk cage to the top" (page 63), ..."

Well, I tested by filling all slots in the bottom 4 disk cage, but still,
the prtdiag won't see the disk in the upper slots. 

Thanks for everybody who replied.

Regards,

Ioan

Subject: SUMMARY: Solaris 9 Sparc iSCSI Initiator - Options ?
Message-ID: <bea9280b0707051651h3f1e9118l2c96666818de10a1@mail.gmail.com>

Hi all,

I had submitted this query in the "fairly recent" past and had gotten
on answer back which I summarized to the list (basically - Cisco has
an EOL iScsi initiator for Solaris9 but not many other options exist)

Since then I did some testing in a related vein which I have found
interesting enough that I think it should be summarized back to the
list as an "addendum" on this topic, with the hope that this is of
interest to other sunmanagers.

I've tested and deployed a solution based on "AoE"
(ATA-over-Ethernet), using a generic Linux server as the AoE target
(which is "exporting" 6x500gig drives in a raid6 array of approx
1.9Tb) and then using the free AoE initiator for Sparc Solaris package
to access this storage.

The deployment/use/functionality is similar to iSCSI but it is a
better fit for my needs (better performance; software is still under
active development - for starters).  The net result has been
"gig-ether-mediated-direct-attached" storage on my e4800 server of
performance better than expected/desired, with really simple
setup/deployment (and a very low cost :-)

Notes are attached below which illustrate the (trivial) process
involved in doing this.

Certainly I believe kudos are in order for the folks @ Coraid (who are
keen on AoE and are developing AoE software for many platforms,
including solaris).

I hope this is of some interest to someone possibly,

---Tim Chipman



-----------paste----------------
Basic Context:

-AoE target (which exports block device storage) is a generic CentOS
(RHEL) Linux box

-AoE initiator (which imports the block device, and uses the disk
capacity as a "direct attached" storage - is Solaris9 Sparc e4800
server

-connectivity is via regular gig-ether (no jumbo frames currently, nor
trunking etc.)

Steps involved are detailed below:

(1) linux box (centOS RHEL5 64-bit - absolutely minimal server install
but with "kernel-devel" and "gcc" packages added)

(a) Setup AoE tools: userspace tools to help evaluate status of AoE
(probably not essential)
root at linux# make; make install

(b) Setup vblade: userspace binary which allows export of local block
devices via AoE:
root at linux# make ; make install

(c) start vblade and "export" metadevice /dev/md0 (software raid6 1.8 Tb):
(syntax note - 1 1 refers to "shelf and tray" id of the "AoE
Blade";used in addressing the device from AoE clients)
root at linux# vblade 1 1 eth1 /dev/md0 &

(2)  Then setup your AoE Client (Solaris 8/9/10 sparc-intel)

(a) install the binary package pre-compiled AoE software:
root at sun# pkgadd -d ./CORDaoe-1.3.2

(b) Configure the NIC to use for AoE and then start the service:
root at sun# echo "aoechan 0 ether skge0" > /etc/aoe.conf
root at sun# /etc/init.d/aoe start

(c) Probe to see that disk is visible:
root at sun#  aoectl list
0/1/1

(d) Label the disk, a kludge required since >1Tb
root at sun# aoelabinit /dev/rdsk/cad101s0

(e) Now we can see the thing via "Format" correctly:

root at sun # format
Searching for disks...done


AVAILABLE DISK SELECTIONS:
      0. c0t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>

...etc....
      9. cad101s0 <Coraid E therDrive vblade  201>   <== this is the AoE "disk"
         /pseudo/aoed at 101

Specify disk (enter its number):


(f) Format and mount: Takes approx 3-4 minutes:

root at sun # newfs /dev/rdsk/cad101s0
...output truncated here ...
root at sun # mkdir /data/aoe-disk
root at sun # chmod 777 /data/aoe-disk
root at sun # mount /dev/dsk/cad101s0 /data/aoe-disk

Verify we see it OK:

root at kt-4800 # df -k

For fun, Do a few tests with Bonnie:


root at sun # cd /data/aoe-disk ; /opt/bin/Bonnie -s 1024 -m aoe-nas
...etc... for each local disk being tested...

note the nfs-nas is an older external 3rd party NAS device running on
8x300gig Raid5 via gig-ether connectivity (of known mediocre
performance)

int-sun is a 6250 sun disk array (fibre disks and fcal connectivity,
effectively a t3 variant I think)


Misc Hardware Notes: Linux box is running on very basic hardware: asus
AM2NPV-vm mainboard, Sempron 1800mhz CPU, 1gig ram, 6x500gig drives
(4xSata and 2xATA) - 500gig chosen because they are very affordable at
approx $130 each, although 750gig disks could be used just as easily
to create a larger array of approx 2.8Tb capacity with Raid6 type
config.  Connectivity is via onboard gig-ether which does NOT seem to
support jumbo frames. I plan to add a dge-530t gig-ether NIC which
does support jumbo frames - hopefully for some slight improved
performance and/or reduced load on servers.

The e4800 has a Syskonnect skge 9821 type PCI nic, something I'm fond
of (they tend to work well and are a good price).

Note that for connecting  the AoE you should ideally have either (A) a
spare gig-ether nic in your solaris machine, or (B) a gig-ether nic
which is fairly idle and is on a "trusted" subnet.


------ORIGINAL POSTING asking about iScsi---------------
 Hi all,

I'm looking at the prospect of using iSCSI to provide storage to a
somewhat aged Solaris8 (enterprise 4800) server in our department, but
I am having trouble getting a handle on my options for iSCSI Initiator
software.

Google indicates there is lots of support for iSCSI (both initiator
and target) in Solaris10, but I get the feeling Sun hasn't back-ported
any of this stuff.

Most open-source iSCSI initiator projects seem focused on Linux.

I gather one option I may have is the Cisco iSCSI initiator, which I
gather may be now somewhat out of favour (at least on platforms where
other options exist?)

I am simply curious if anyone else has been using iSCSI initiator
software (free ideally) on production Solaris 9 Sparc platforms, and
if so, any pointers on what was used (and how implementation has
been!?) -- would be greatly appreciated.

Many thanks,

--Tim Chipman

To set persistent binding on the qlc driver we had to set in /etc/system

set fcp:ssfcp_enable_auto_configuration=1

After this we were able to discover new luns/vpaths online (without
doing a reboot),  by doing:
devfsadm
/etc/rcS.d/S65-vpath-config

Rebooting the system didn't reshuffle the vpaths.
We test this procedure on a testbox.

The official statement of Ibm is that online discovering of luns is not
possible with Solaris 8,
only since Solaris 10 this should be possible :-(

Onderwerp: online discovering new luns Sun box with Ibm SVC


Hi,

We have a Solaris 8 machine connected to an IBM SVC (version 4.1).
Behind the Ibm Svc there's a DS8300 storage cabinet. The Sun machines
has Sun branded Qlogic cards (QLA2310F-SUN), we are using the qlc-driver
for the hba's and the Ibm sdd driver in stead of mpxio. We also use
Disksuite (SVM) as volume manager.

We faced some strange problems when connecting  the Sun to the Ibm
storage. In the Ibm documentation there is a procedure to discover new
luns online. Unfortunately when we try is (devfsadm; rm /etc/vpath*cfg;
cfgvpath -c ;
/etc/rcS.d/S65vpath-config) we will see the new luns and we can add a
new filesystem. But after a reconfigure reboot all the disks are
reshuffeled :-(

When we don't try to discover the new luns online, just map the disk and
do reboot -r everything is fine. Don't like it to reboot a server for
discovering a new luns, but for this a fact of live.

Did anyone had  same problems?

In the Ibm documentation we cannot find anything about the qlc driver,
only the qla2x00.conf is mentioned. Does someone know how to set
persistent binding on the qlc driver?

I'm also wondering if anyone has a Sun box connected to Ibm Svc. What's
your experience with it?

Many thanks.
Klaas

Hi all,

In the end I received only two answers, both of which contained suggestions 
that I had already tried.  

In the end, I gave up trying to recover the "lost" storage pool.  There seems 
to be no possibility to recover a zpool from another system when that system 
fell over.  

Thanks

you can also alter this file as root using the GUI dtpower, IIRC.

My standard new system setup makes these edits early on, and there's a
reboot at the end of the setup, which would restart the daemon.  I don't
remember if there's a way to make the changes take effect without a
reboot.

Install SAN package from SUN (install_it) and reboot the server. 
Activate the SUN licensing on the IBM FASTt, configure LUN for the server
and everything works fine after!

  I have no problem configuring the SAN/FASTt but about Solaris i'm 
  totally lost!
  
  The server is running Solaris 9!   If you can help me feel free to send 
  me an email, I will do a summary to the list!

Subject: SUMMARY: Solaris 10, Oracle 10G, Shared Memory Segments
In-Reply-To: <46A10117.2030106@emc.com>
References: <46A10117.2030106@emc.com>
Message-ID: <46A4B3B5.2060002@emc.com>

 Hello All,

Our DBA's were able to uncover the mystery for us. It seems that Oracle,
running on Solaris 10, has purposely broken up the SGA into multiple
segments for performance improvements. See Oracle Metalink Note: 399261.1
(10G SGA is split in multiple shared memory segments). To disable this
"feature",

_enable_NUMA_optimization=FALSE in the Oracle parameter file...

We are going to test this change ourselves, to see if there is an actual
improvement running multiple segments.

For those without MetaLink access, here is the important information from
the note...

...snip....
Applies to:
Oracle Server - Enterprise Edition - Version: 10.1.0.0 to 10.2.0.3

10g SGA is split in multiple shared memory segments
In 10g NUMA optimization is enabled by default while in 9i it is not
because of this we see multiple segments in 10g. NUMA optimization  is
set by parameter _enable_numa_optimization=true in parameter file.

This use of multiple shared memory segments is expected in 10g for
performance reasons.Where we create 1 per process group (lgrp to use sun
terminology) and 1 that stripes across all lgrps and one that is a really
small bootstrap segment. Performance should be better with multiple
segments.
NUMA optimization is an internal optimzation on the way the data
structures are laid out and how the buffer cache is laid out such that we
reduce the total number of remote cache misses on a large system.
If you want the database to start with a single segment, then set
_enable_NUMA_optimization=FALSE.

....snip....

Thanks.

   Hello,
  
  Has anyone else noticed the following behavior regarding Oracle's use of
  shared memory, specifically around the shmmax (Solaris 8) and
  shm-max-memory (Solaris 10). Before we upgraded our servers from Solaris
  8, our Oracle 10G databases were grabbing just 1 large shared memory
  segment for the database. For example, this is what ipcs said while
  running the DB on Solaris 8:
  
  T         ID      KEY        MODE        OWNER    GROUP  CREATOR   CGROUP
  NATTCH      SEGSZ  CPID  LPID   ATIME    DTIME    CTIME  ISMATTCH
  Shared Memory:
  m      19458   0xcf1bb170 --rw-r----- oracle dba oracle dba    790
  31138578432 21097 22653 10:47:09 10:47:09  7:52:43      790
  
  After "Live Upgrading" to Solaris 10, and converting all our old
  /etc/system settings to the new /etc/project format, we are noticing that
  now Oracle is grabbing the same "total" size shared mem segments, but
  instead of just 1, it is being split up into multiple ISM segments?
  
  T         ID      KEY        MODE        OWNER    GROUP  CREATOR   CGROUP

  Has anyone run into this? We are not sure if this is a Solaris 10
  problem, or an Oracle issue? Sun Support is saying that have not seen
  this before.
  
  Any solutions out there to get Oracle back to using just 1 large shared
  memory segment?
  
  My last thing to test will be to put the old shmmax variable into
  /etc/system, and reboot to see if that magically fixes the situation?
  
  Thanks.

All -



Thanks for all the responses to this issue.  It turned out the issue was
a improperly configured nsswitch.conf file.  The server don't use DNS
and both files, dns were set in this file.

 I just use a old PC with Windows and Hyperterminal using a serial

Thanks!

-------------------------------------------------

Hi guys,

I'm very new to solaris, and we just buy 6 enterprise 420 servers.   But
I have a simple and easy question, can I use any dumb terminal to
configure the machine or I really need a SUN terminal?

And if I can use any terminal, what is the pinout I need to be able to
use it!?   I just try a IBM 3151 Terminal but I can't see anything on the
terminal!   And I think I need to do STOP-A to be able to boot from the
CD, but how to do a STOP-A from a non-SUN terminal ?

Thanks!

Don Radliff nailed it on the head when he said:

       Hi Jason, i think you need to use a straight thru ethernet cable
instead of the cisco one..

I forgot I could use a straight through ethernet cable with the correct
adapters
in lieu of a serial/null modem cable. The adapters I used were:

Silver Sun RJ-45/DB-25 P/N 530-2889-03
Grey RJ-45/DB-9 P/N 74-0495-01

Grabbed a straight through ethernet cable and BANG, everything worked!

Thanks also to the following for their excellent troubleshooting
suggestions:

Thank you for the responses.

Basically you have to do tagging of packets for something like this to
work.  I wasn't sure if with all the changes in Fire Engine if maybe
this was possible now.  it isn't, at least not in any practical sense
that I would implement.

Hello All,

Thank you for all your help. I had over 20 replies on this one.
The conclusion to this problem is that when the server boots up it uses the
first nic by default. the only way the 2nd nic
(on the same network segment) is activated is by administratively shutting
down the 1st int.

The whole reason behind this little experiment was to trouble shoot my
original problem. I'll be writing this up and posting
it shortly.

Cheers!
Sashah.
