Replacing a Failed Disk Drive
007-4644-001 47
7. Review all documentation shipped with the new drive module for updated
replacement procedures and other information. If necessary, modify the remaining
steps to meet the system requirements. Kits often contain the most current servicing
information. If the kit instructions conflict with those in this procedure, follow the
kit instructions.
Caution: If the temperature of the shipping or storage environment differs
significantly from the temperature of the environment in which the drive module
will be installed, acclimate the drive module before you install it.
8. Wearing antistatic protection, slide the new drive module fully into the slot.
Caution: Partial insertion of a drive may cause the controller to mark other drives
on the same bus as failed. Install a drive in one complete motion. Make sure that you
insert it all the way into the slot and lock it into place.
9. Lower (close) the lever. Wait for the new drive to spin up.
10. Check the drive activity and fault indicators above the new drive module. The
activity indicator should be on (either blinking or steady) and the fault indicator
should be off.
Note: The fault indicator may flash intermittently while the drive spins up. The
activity indicator blinks when data is being written to the new drive module.
• If the activity indicator is off, the drive module could be installed incorrectly.
Remove the drive module, wait 30 seconds, and then reinstall it.
• If the fault indicator stays on, or if the activity indicator stays off, the new drive
may be bad. Use TPSSM to determine the problem.
11. See the applicable software procedures (for TPSSM or other system software) for
instructions on bringing the drive module back online.
Important: Depending on your storage array configuration, the storage array may
automatically reconstruct data to the new drive module. If the array uses hot spares,
it may have to complete reconstruction on the hot spare before it copies the data to
the replaced drive. This increases the time required to complete this procedure. Use
TPSSM to determine the current status of the new drive and the progress of any
reconstruction or copyback.
