3-34 Sun StorEdge 5310 NAS Troubleshooting Guide • December 2004
Caution – Potential volume group failure. The command module supports a
maximum of eight drive modules per loop (112 drives maximum). Do not install
new drives into the empty drive slots in the command module enclosure if the
module is already at the maximum configuration. Doing so will exceed the fibre
channel protocol limit and cause volume groups to fail.
Caution – Electrostatic discharge damage to sensitive components. To prevent
electrostatic discharge damage to the module, use proper antistatic protection when
handling the module components.
Caution – Potential damage to drive components. Drives can be damaged by
bumping them into other objects or surfaces. When removing or installing a drive
into the drive module, place your hand under the drive to support its weight. Place
drives on an antistatic, cushioned surface.
1. Put on antistatic protection.
2. Unpack the new drives that you intend to install.
Set the new drives on a dry, level surface, away from magnetic fields. Save all
packing materials in case you need to return the drives.
3. Locate the blank drives in the command module.
Check the Drive Active light on the front of the command module. On an active
drive, a green light will be on or flashing. On a blank drive, the light will be off.
Note – IMPORTANT When replacing a blank drive with a new drive, replace the
first available blank drive from the left, looking at the front of the module.
Functional drives occupy the slots to the left; blank drives occupy the slots to the
right.
Caution – Risk of potential data loss. Removing the wrong drive can cause data
loss. Remove only blank drives. If you accidentally remove an active drive, wait at
least 30 seconds, and then reinstall it. For further recovery procedures, refer to your
storage management software.
4. Lift the locking lever on the blank drive and remove the drive from the slot.
5. Slide the new drive all the way into the empty slot and close the drive lever.
As the drive spins up, the Fault lights may flash intermittently. A flashing Active
light indicates that data is being restored to the new drive.
