Operating Systems AIX IBM SAN STORAGE HOT SPARE DISK Post 302604176 by filosophizer on Saturday 3rd of March 2012 12:30:00 PM

a quick question:

I have one free disk plugged in the SAN Storage. It is not part of any array or hotspare coverage ( I have removed it from hotspare coverage -- )

Can I just remove the disk while the SAN is powered on and plugged into the failed disk ?

or

Do I need to shutdown the SAN Storage and remove the disk ?

--------------------
SOLUTION:

1) You can remove / unplug an ununsed powered Disk from the SAN STORAGE and use it in place of failed disk without powering off or anything

2) You can make the HOTSPARE a permanent disk provided this option is supported by the firmware level and software of DS4000

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME
volunroot - Remove Logical Storage Manager hooks for rootable volumes SYNOPSIS
/usr/sbin/volunroot [-a | -A] OPTIONS
Specifies that all volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and swapvol. Forces removal of the private region unless it is the last one in the system. DESCRIPTION
The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk directly through disk partitions instead of through volume devices. The script also removes other changes that were made to enable booting of the system from the root volume, so that the system will boot with no dependency on the Logical Storage Manager. When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol. For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by volrootmir or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions defined for them on the disk. If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions. The unwanted plexes can be removed using either voledit or volplex. SEE ALSO
