Removing and Replacing FRUs
Exchanging Disk Drives
When a maintenance procedure requires you to replace a faulty disk drive with a new
one, first check whether the disk drive to be removed is a member of a RAID array.
If the disk drive to be changed IS NOT a member of an array, go to “Exchanging
an Array Disk” on page 20.
If the disk drive to be changed IS a member of an array, go to “Exchanging a
Non-Array Disk Drive.”
Replacement Disk Drives
There are two points to note about a disk drive you are installing to replace a faulty
unit.
If the replacement disk drive is a new unit from the factory, or one previously used
in an AIX machine, it will be placed on the list of New Resources. It must be
converted to a Free Resource before it can be used by the PC.
If the replacement disk was previously formatted as a member of a RAID array in a
different system, it will be identified as a Pre-Configured disk. It must be converted
to a Free Resource before it can be used in the new system.
Exchanging a Non-Array Disk Drive
The procedure depends on whether you are using the DOS configurator or the RSM
configurator.
Using the DOS Configurator
1. From the Main Menu, select SSA Adapter List
2. Select the required adapter from the list displayed.
3. From the Adapter Menu, select Disk Service Aids.
4. Select the disk drive that you want to change.
If necessary use the Identify function to find the disk drive. Press F9 (FlashOn);
the Check light flashes on the selected disk drive; press F10 (FlashOff) to remove
the function.
5. Put the disk drive into Service Mode.
Place the cursor on the disk drive entry and press F4.
6. Remove the old drive and replace it with a new one (see the unit
Hardware
Maintenance Manual
).
7. Press Esc to exit from the Service Aids window.
This action automatically resets Service Mode on the new disk drive.
