I am getting multiple 'csimgr replace_wwid' messages in our Unix servers which have external storage assgined. There are many class : lunpath, instance ids.
Is there any way I can get rid of these instance IDs in one shot or do I have run the 'csimgr replace_wwid' commands for each of the Lun instances.
Solved! Go to Solution.

Re: scsimgr replace_wwid messages
Re: scsimgr replace_wwid messages
class : lunpath, instance 1794
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 = 56) The lun path is (class = lunpath, instance 1794).Run 'scsimgr replace_wwid' command to validat
e the change
Due to this the server is not ablet to detect the newly assigned LUN.
There are hundreads of such messages. Is there any way I can successfully bind all the Lun Instances using the scsimgr replace_wwid command or do I have to run the command individualy for each lun instance ids

Re: scsimgr replace_wwid messages
During lun assignment , zoning , mappng you may may see the error messages in syslog or dmesg,
You can check the status if they arestill disabled or ok with :# scsimgr -D get_info /dev/rdisk/diskxxx
if disabled you can try enabling it with enable command or binding the lunpath.

Re: scsimgr replace_wwid messages
Re: scsimgr replace_wwid messages
You can easily identify what target path instances your LUNs are associated with by running "ioscan -fN" and you will see what lunpaths are under which target path instance numbers (to just see the target path instances try "ioscan -fNC tgtpath")

#scsimgr -f replace_wwid -D /dev/rdisk/disk3546
scsimgr: Successfully validated binding of LUN paths with new LUN.
But again in ioscan output the disks shows up as no_hw. Once the validation is done, shouldnt this no_hw disappear from the ioscan output.
#ioscan -N -n -f |grep -i no_hw |grep disk3546

Re: scsimgr replace_wwid messages
Generally NO_HW entries in ioscan don't go away until the next time you reboot... shouldn't be a problem though.
