4. Replace the failed module by following the instructions in “Removing a Drive
Module” on page 106.
You can also use the CLI

is “Absent” the drive might have failed, or it has been removed from the chassis.
For details on the
show enclosure-status
command, see the CLI reference
guide .
Removing a Drive Module
When you remove a drive module, it is important to maintain optimum airflow
through the chassis by either replacing it immediately with another one or by using
an air management module. If you do not have a replacement module or an air
management module, do not remove the drive module, that is, it is not harmful to
the storage system to keep a fault drive inserted until you have a replacement drive.
If you do have an air management module, it is installed using the same procedure
for removing a drive module as described below.
Caution – If you remove a drive module and do not replace it within two minutes,
you alter the air flow inside the enclosure, which could cause overheating of the
enclosure. Do not remove a drive module unless you have a replacement drive
module or air management module to immediately replace the one you removed.
To remove a drive from an enclosure, perform the following steps:
1. Follow all static electricity precautions as described in “Static Electricity
Precautions” on page 80.
2. Squeeze the release on the left edge of the drive ejector handle.
3. Rotate the handle toward the right to disengage the drive module from the
enclosure’s internal connector.
