2. RAIDYNE activates the so-called fail operation mode. In this mode, the disk array re-

mains fully operational. The data of the failed drive is reconstructed by means of the re-

dundancy information stored on the other drives.

3. RAIDYNE starts the motor of the Hot Fix drive.

4. RAIDYNE includes the Hot Fix drive into the disk array and starts to reconstruct the data

and redundancy information. The disk array is now in the operation mode rebuild.

5. The alarm signal is not turned off until a new Hot Fix drive is added to the disk array, or

until GDTSETUP (or GDTMON) is loaded and the missing Hot Fix drive is removed or re-

placed with a new one.

Obviously, no other hard disk may fail until all data is entirely reconstructed on the Hot Fix

drive, because up to that moment the system operates without redundancy.

How is this situation reflected in GDTSETUP?

What has happened to the failed drive ?

To answer these and other questions we load GDTSETUP and check. We go directly to the

menu Configure Array Drive menu. As expected, the disk array is in the rebuild state. Request

the drive information regarding the RAID5 disk array with <F2>.

Two changes have occurred. The Hot Fix drive DISK_C2 has the state invalid and has jumped

into the position of DISK_B2. DISK_B2 is missing (this is the drive we let fail (disconnected

it from the DC power). Since this disk array was configured to have a hot fix drive, this posi-

tion is still in the list, with the attribute missing.

Leave GDTSETUP and when you are back at the MS-DOS prompt, switch off the system. We

now want to add a new Hot Fix drive to the disk array. For our example we take a brand new

drive, set its SCSI ID to 3 and connect it to the connector of SCSI channel B, where the pre-

viously failed drive was connected to and to the DC-power supply. Before switching on the

system again, check that the SCSI termination of the new drive is identical to the old one.

After switching on the system again, load GDTX000 and GDTSETUP and initialize the new

drive.
