The Hot-Plug Procedure

These are the steps required to properly hot-plug a disk drive:

Step 1

• Check if the LVM found the physical volume to be defective when the volume group was

activated.

• The “vgchange -a y” command would have printed the following message on the

console:

WARNING:

VGCHANGE:WARNING: COULDN’T ATTACH TP THE VOLUME GROUP

PHYSICAL VOLUME “/DEV/DSK/cXtXdX”

THE PATH OF THE PHYSICAL VOLUME REFERS TO A DEVICE THAT DOES NOT

EXIST, OR IS NOT CONFIGURED INTO THE KERNEL.

• If the status of the “vgchange -v vg02” is unknown, you may check if this occurred by

doing a vgdisplay command:

vgdisplay<

VG name

For our example:

vgdisplay /dev/vg00

• If the disk was defective at vgchange time, the following messages

will be printed one or more times:

WARNING:

VGDISPLAY: WARNING: COULDN’T QUERY PHYSICAL VOLUME

“/DEV/DSK/cXtXdX”

THE SPECIFIED PATH DOES NOT CORRESPOND TO PHYSICAL VOLUME

ATTACHED TO THE VOLUME GROUP.

VGDISPLAY: WARNING: COULDN’T QUERY ALL OF THE PHYSICAL

VOLUMES

• If you see these messages, the disk was defective at the time the volume group was

activated.

Otherwise, your disk became defective after the vgchange and you must continue with

step 2 of this procedure.
