Removal and Replacement

# vgchange -a y <volume group name>

For example:

# vgchange -a y /dev/vg00

Tools

■ ESD wrist strap (no hand tools are required to perform this procedure).

Whenever possible, follow ESD procedures.

Procedure

Caution Whenever possible, follow standard ESD procedures and avoid

touching exposed circuitry.

Do not remove a disk or filler from an operating product until you

have the replacement part and are ready to install it. An empty slot

will cause uneven cooling and overheating.

1 Release the disk module from the slot by squeezing the latch tab (see

Figure 57) and pulling the disk module toward you.

Caution Spinning disks generate heat and gyroscopic force.

Wait for a spinning disk to slow down and cool off before

removing it from the product.

WA RN IN G High current available. Avoid touching the midplane or adjacent

drive electronics when removing and inserting disk modules.

2 Pull the disk out of the slot using the extraction handle. Support the disk

module with your other hand around the enclosed side. See Figure 57.

Note Removing disk modules and fillers from right to left improves

access to successive disk modules.
