Module Replacement

 

 

NOTE! An important side effect of the

commands is that the LVM configuration

backup file used by the

command in step 3 is updated. If this hot plug procedure

is being performed now on another host system and there was no need to execute lvreduce commands, then the configuration file has not been updated. However, the LVM

vgcfgbackup command.

Step 4

he replaced disk module to the active volume group with the

vgchange

#vgchange a y <volume group name>

#vgchange a y /dev/vg00

Note for MC/ServiceGuard If the disk array is used in an MC/ServiceGuard cluster volume

 

vgchange –

/dev/vgcluster

 

 

VG Status from the vgdisplay:

Step 5

 

 

6. If the disk is the mirror of a root disk:

a.mkboot command on the replaced disk.

If you use the example from “Example of a Disk Module Failure”, the host will display:

# mkboot /dev/rdsk/c2t4d0

Run the

-R

-link the replaced disk into the Boot Data Reserved Area of all

# lv1nboot

R

mkboot and

-R

commands are repeatable with no harm.
