Adding Drives of Larger Capacity
This section provides guidelines for upgrading the disk drives in a storage array.
Carefully read your software documentation and this entire section to determine if you
should follow this procedure, a modified version of this procedure, or use a different
procedure provided by your operating system. Instructions provided with your software
should supersede the instructions in the section.
Warning:
Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling enclosure components.
The only method for upgrading disk drives is to replace them all at the same time. This
method requires you to back up the enclosure and shut down the storage array before
replacing the drives. After replacing all the drives, you must reconfigure the enclosure
and restore the data from backup media. This is the safest way to exchange drives
without losing data. However, this method may take a long time to complete because of
the backup, reconfiguration, and restoration processes. In addition, other users will not
be able to use the enclosure until you finish the procedure. You must use this method on
RAID 0 logical units (LUNs).
Follow these instructions to replace all drives at the same time. All the data currently on
the drives will be lost when you replace the drives. You must use this method if you are
upgrading drives containing RAID 0 volumes.
1.
Read the following:
•
“Upgrading Drives” on page 59.
•
Information in your software documentation.
•
Documentation shipped with the new drives.
Read all precautionary notes, kit instructions, and other information. Kit
instructions often contain the most current information regarding the drives and
their installation, plus upgrade or servicing procedures. Compare the kit
instructions with this procedure to determine if you need to modify this procedure.
2. Check TPSSM and repair all reported problems.
3. Perform a complete backup of the drives that you are replacing. You need the
backup to restore data on the drives later in this procedure.
