Maintenance and Service Guide
If a disk drive is replaced after the array controller is off, install the replacement
disk drive before restoring power to the array controller. After the power is
restored, use the
DELETE container-name CLI command to remove the disk
from the configuration. Then, use the
ADD DISKS CLI command to add the new
disk drive.
Disk drive hot swap support
Disk drive hot swapping is supported only if the following conditions are met:
■ Array controllers are not engaged in Failover or Failback.
■ Array controllers are not running a local utilities such as DILX or VTDPY.
■ The array controller CLI prompt is accessible (not while a previous CLI
command is being processed).
■ If the disk drive being removed or replaced is physically moved to a new port
or target location on the same array controller, you must wait a minimum of
60 seconds before re-inserting device into its new location.
■ If the array controller is in the process of recognizing or processing one or
more hot disk drive insertions, the array controller must be allocated enough
time to do proper device discovery for both operations. The busier the array
controller, the longer the waiting time should be. (One disk drive at a
time—waiting 60 seconds between physical removal or replacement
operations).
■ Do not remove a device from a unit that is under load (including
reconstruction and initialization). If you want to remove a device from a unit,
you must reduce the RAIDset or mirrorset and delete the diskxxxxx
device.
Disk drive warm swap support
Disk drive warm swapping is supported under the circumstances described below.
Abide by the following rules related to disk drive removal and disk drive insertion
into HSG60 or HSG80 subsystems. Promptly execute the procedure so that the
internal detect swap signal terminates the quiesce functionality.
Disk drive warm swap
If disk drive hot swapping is not applicable, use disk drive warm swapping. Also,
from a data integrity perspective, the best method of physically removing a device
in a parallel bus multi-drop architecture (such as a SCSI bus) is to use a warm
