emc clarion lun doesnt detects in hpux 11iv3

Dear All,

 

We have HPUX 11.31 running on Blades and RX3600. We are facing strange issues on lun detecion. Whenever storage team assigns a lun to the system, its only being detected if we reboot the server, any help will be appreciated.

Error from syslog -

Sep 21 15:44:29 usdadwwsppuh0 vmunix:
Sep 21 15:44:29 usdadwwsppuh0 vmunix: class : lunpath, instance 47

Hi,

check the compatibility matrix. emc firmware looks.

must have a minimum level of firmware.

If you want to avoid the reboot, you have to use scsimgr replace_wwid commands as described in the syslog message.

 

So for example if it says this:

Sep 21 15:44:29 usdadwwsppuh0 vmunix: Evpd inquiry page 83h/80h failed or the current page 83h/80h data do not match the previous known page 83h/80h data on LUN id 0x0 probed beneath the target path (class = tgtpath, instance = 26) The lun path is (class = lunpath, instance 47).Run 'scsimgr replace_wwid' command to validate the change

You have to run this command:

scsimgr replace_wwid -C lunpath -I 47

Do this for every lunpath that has such a message in syslog and the LUNs will be visible without a reboot.
