Adding Drives to Empty Slots

114
You can upgrade drives in two ways:
• Add drives to empty slots in the drive enclosure (see "Adding Drives to Empty
Slots" on page 114).
• Replace existing drives with larger capacity drives (see "Adding Larger Capacity
Drives" on page 115).
Use this procedure to install additional drives into empty slots in the drive enclosure.
You can install additional drives while the drive enclosure is powered-up and running.
Caution: Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling drive enclosure components.
1. Read the pertinent information in the software manuals supplied with your system
regarding drive upgrades and installation.
2. Check the storage management software (TPSSM7) and repair all reported
problems.
3. Locate the blank drive sleds.
• Because the blank drive sleds contain no drives, their Activity indicators (on the
front bezel above the drive sled) will not be on.
• Verify these drive positions are blank using the storage management software
(TPSSM7).
Caution: Removing the wrong drive can cause data loss. Make sure you remove
only the blank drive sleds.
If you remove an active drive accidentally, wait at least 30 seconds and then reinstall
it. Refer to the storage management software (TPSSM7) for further recovery
instructions.
4. Wearing antistatic protection, lift (open) the lever of the blank drive sled.
