DF Disk Module Replacement Requirements
To replace a disk module while the host is operating, all of the following conditions must be met:
• All patches must be loaded by an HP service representative or customer engineer (CE).
• All of the extents of the replaced disk that are in use must belong to mirrored logical volumes that
were created with the strict (-s) option.
• You must have a current volume group configuration backup file. In version 10.x, the backup is
created by default each time an LVM command changes the LVM configuration. The default backup
file path name is: /etc/lvmconf/base_vg_name.conf. In version 9.x, the backup is a manual
process.
• The replacement disk module must be of the same or greater capacity as the module being replaced.
NOTE! HP uses different manufacturers for disk modules having the same product number.
The manual hot plug procedure will not update the disk module internal information to that of the
replaced disk. A replacement disk module must have the same capacity and block size as the
defective disk module because it has the same product number. The only string that can be
different is the one specifying the vendor name. This will not affect the behavior of the LVM. If
you want to update the manufacturer's name, the disk's volume group must be deactivated and
reactivated.
If the conditions listed above cannot be met, contact your HP service representative for help.
