Chapter 2. Adding or migrating hard disk drives
To add hard disk drives to the storage subsystem configuration or place the drives
(that made up a RAID array) in different drive bays, see the following sections:
v
To add new hard disk drives to an existing storage subsystem, see “Adding new
hard disk drives” on page 14.
Note:
Any hard disk drive might contain configuration data. Unless you intend
to migrate drives from another storage subsystem (retaining its configuration
data), always use this procedure to add hard disk drives to an existing storage
subsystem configuration.
v
To add new unassigned drives in different drive bays, see “Adding new hard
disk drives” on page 14.
v
To migrate drives from one storage subsystem configuration to another, see
“Migrating hard disk drives” on page 15.
v
To rearrange the drives (that made up a RAID array) in different drive bays in
the same storage subsystem, see “Migrating arrays within the same storage
subsystem” on page 21.
Before you begin, review Chapter 1, “Prerequisites to adding capacity and hard
disk drive migration,” on page 1.
Considerations
The following notes describe information that you must consider when you add a
hard disk drive to a controller or a storage enclosure:
v
Observe proper electrostatic discharge (ESD) procedures when you handle
electronic equipment. For more information, see “Handling static-sensitive
devices” on page 14.
v
Never alter the physical configuration of a storage subsystem while the power is
turned off unless you are instructed to do so as part of a configuration
procedure. Specifically, never attach storage components to, or remove storage
components from, a configured storage subsystem while the power is turned off.
v
Updated readme files contain important configuration and procedural
information that supersede information in this document. Always check the
readme file before you perform any procedure or activity described in this
document. To access the most recent readme file, see “Finding Storage Manager
software, controller firmware, and readme files” on page 57.
v
Before you migrate hard disk drives, complete the following steps to establish
drive model compatibility:
1.
Check the drive CRU form factor options.
2.
If the form factors are not the same, there are no replacement parts such as
bezels and drive trays. For more information, see the announcement letter,
the Installation, User's, and Maintenance Guide for your storage subsystem, and
your IBM marketing representative or authorized reseller.
3.
If the form factors are the same, check to determine whether the drive is
supported by the storage subsystem.
4.
Ensure that the drive can operate at the storage subsystem drive
loop/channel Fibre Channel or SAS speed. For more information, see the
