emc clarion lun doesnt detects in hpux 11iv3

[Madan Kumar]

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 -

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.
