Would like to expand one of partition which is alread on SAN, and already 
assign another 100 gb, but on Solaris 10, using format, couldn't see that 
new 100gb disk.
even after reboot, still can't see new disk,

What could be wrong? And how to know the disk has been added correctly?

Thanks a bunch. 

If you mean you did this using another cable, then run "iostat -xn" to
see if you see anything extra. If does, run "devfsadm -c disk -v". If
does not from iostat, you may need to figure out to add this new SAN
initiator to your box.

If you mean you added a single disk to one of the SAN arrays, you may
deal with that using EMC software.

Regards
Victor

I'm confused... Did you expand the LUN or did you add a second lun?

Are you using EMC power path?

Could you show us the related messages in /var/adm/messages?

Victor

Sorry to confuse you guys.
The fact is,

One of SAN (EMC) guys gave another addtional 100gb space to Solaris box
(10) from SAN array, and I need to expand one of partitions which is
mounted from SAN.

I did "devfsadmin -c" and format, but couldn't see that extra space
(hard drive).
Was suggested by rebooting solaris, but still luck finding it.

Yes, it is using EMC power path.  What could be wrong?

If disk from SAN added correctly, will it change "sd.conf" file
automatically?

Please help.

Hmm, exam question perchance?

May or may not.  Our vendor even suggests to add up to 256 targets in
sd.conf if things do not work out, but it did not happen to us.

If your SAN guy could confirm that 100gb was added in his side, the
worst scenario is to start over to connect to your SAN.

Victor

Thanks Victor,

How to start over to start over to SAN?

How to tell if the disk has been added correctly? Any file gets changed when 
SAN guy added extra disk space?

I do not know EMC. Would you like to call EMC?  The iSCSI card we get
is from QLogic. It has its driver and management software.  We had
different issue and I restalled the driver and software twice.  Maybe
you need to read the manual first because sometimes the technical
support is not good enough and you have to twist it out by yourself
like us.

1. At first runa luxadm probe to see the HBAs.

2. Then try with /etc/powermt display dev=all --- to see the current
paths.

3. With devfsadm -C you will recognize the new devices. If you are
thinking about rebooting the system try on this way: reboot -l -- -r

4. Check using format y you have any news.

5. In order to do a further research I would try probing the devices
from the OBP.

Good Luck!
Sebastian.

More likely just someone having problems getting Solaris to see a newly
presented LUN.  We have them, that's for sure.

Mostly likely there is no file indicating these if "format" could not
see these changes.  Right now although your SAN guy have seen this
extra 100gb using his software, maybe he missed one step, e.g. growing
this initiator/device which is similar to "growfs".  If you start it
over, then the problem is absolutely from his side.  Do not forget
backing up before start it.

But I really think EMC should provide assistance.

Good luck!

format doesnt see the drive after reconfig reboot. this is what I am
getting from the OP's post.

OP has to specify if they are using Sun Leadville drivers / using the
Emulex drivers and doing persistent binding and sd.conf entries
manually.  Talk to your SAN guy and have him check if he has forgot any
thing from his end. If he hasn't I would assume it is on the host side
as the host already sees some devices from the SAN.
