Raid array lost one service processor

James F. Kent — Tue, 05 Nov 2002 19:15:01 GMT

When I get my SP replaced how do I get back the original configuration. It doesn't show up in ioscan -fnkC disk any longer. What is the order I should do?
vgcfgrestore vgscan -a or what?

Hi,

do a full and refreshing scan instead of reading from Kernel by "ioscan -fnC disk" (without the "k" option).
Now your disks (which i think are the alternate paths) must show up.
Now you can do a "vgdisplay -v " and see if your config is ok.

Best regards

I assume you are replacing the SP due to a failure? If so, provided nothing has changed on the array, simply do ioscan to force the system to reread the io paths.

James,

If this is an FC array, it may be necessary to run fcmsutil replace_dsk routine to tell the array you know the SP was replaced. You will need the N-Port ID for this. You can obtain this with a tdlist command. The typical symptom of this is a NO_HW under ioscan. Follow the suggestions mentioned first ioscan -fnCdisk (without 'k'). If that shows NO_HW, do a man on fcmsutil.

HTH,

Dave
