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.
