NOTE
Hot-Pluggable Hard Disk Drives
The Hot-Plug Process
The system problem for this example is that the disk at hardware
address 10/0/14/0.0 has a head crash, and as a result, is unusable. The
steps described in the Hot-Plug Procedure section below outline a
method that can be used to recover from this state.
1. All of the replaced disk's in-use extents must belong to mirrored
logical volumes which were created with the "strict" option (-s); see
the documentation for MirrorDisk/UX.
2. You must have an up-to-date configuration backup file. This is done
automatically each
configuration.
The default backup file's path is:
/etc/lvmconf/base_vg_name.conf
3. The replacement disk must be the same product ID as the replaced
one.
HP often uses different manufacturers for disks having the same product
number. The hot-plug manual procedure will not update the disk driver's
internal information to that of the replaced disk.
The replacement disk will have the same capacity and block size as
the defective disk because they have the same product number. The
only field that could be incorrect is the string specifying the vendor's
name. This will not affect the behavior of the LVM. If it is desired to
update the manufacturers' name, the disk's volume group must be
deactivated and reactivated. See the HP-UX System Administration
Tasks manual for details.
