Hi all
I have 2 rack with the same equipment
in both I have 2 rp3440 server with combo fiber card ( A9784A) and one msa1000 with san swith 2/8
I installed hp-ux v1 on all of four servers
in rack A I dont have any problem and both servers detected the msa1000 and disks , but in rack B both server do not detect the msa1000 and both hba card blinking green and yellow.
I changed the fiber cable and also the msa san switch and also hba card with a new one but still i have problem.
both rack configuration is same and i have no error or failuer .
is need necessery if i use any command in hp-ux to detect the msa1000 or anything else?
Please advice me

Did you try to see if the the MSA1000 is detected by BIOS when the server boots.  After the power to the system has been restored, press the Esc key to get to the Boot PROM prompt where Boot_Admin> is offered. At the Boot_Admin> prompt, type search:

Boot_Admin> search [Enter]

This will list the scsi disks

or else check this log file for SCSI devices detected


or try this

# /usr/sbin/ioscan -C disk

For further details you can refer to this article which talks about the above in detail


Perhaps the PSU for the 2/8 SAN switch (which is the MSA1000 chassis) is faulty.

I would connect the serial cable to the embedded SAN switch, 9600,8,n,1,n and login as admin (return for password so it isn't changed) type ipAddrSet and change it from  to a usable value and then connect to it with a web browser. (or you can telnet to to change the IP address if you want as long as you set your server network up for this temporarily)

Then on the web page select fabric manager zoning tool (bottom of left hand pane) and then you should see the WWID of the crossroads controller and of your HBAs. This will verify basic connectivity.

Can you experiment by plugging into the SAN switch in the working rack to test or i it in production? shouldn't cause a problem if it is zoned but could upset the SAN if not.
