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 = 21) The lun path is (class = lunpath, instance 799).Run 'scsimgr repla
ce_wwid' command to validate the change

class : lunpath, instance 800
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

Your system has detected that on this lunpath some device change occurs, LUN id and target id is same but device WWID has changed. This kind of warning message is logged when you replace disk on the system or remove device on the storage and readd with the same LUN. If you are ok with this change you can give the following command to approve the change:

scsimgr -f replace_wwid -C lunpath -I

How to find the WWID

[Turgay Cavdar]

If you type:
scsimgr get_info -C lunpath -I <>

then you will see "Open close state" as AUTH_FAILED. You can also see LUN WWID in the same command output.
