To replace a failed mirrored disk for a mirror set in which the other mirrored disk is active: 1. Acquire a replacement disk that is equal to or larger in size than the failed disk. 2. The replacement disk must be of the same SCSI variety as the failed disk; for example, the old and new disks must both be narrow or both wide. Ideally, the disks should be the same size. 3. Shut down the IOP that contains the failed disk. 4. Remove the failed disk. 5. Install the replacement disk. WARNING Do not modify any SCSI BIOS settings. Your system must maintain the SCSI BIOS settings selected during initial Endurance 4000 installation. 6. Reboot the IOP in Offline Marathon mode. 7. Using the Windows NT Disk Administrator, partition the replacement disk as follows: NOTE Because this disk will be the target of a mirror copy when its IOP rejoins the Endurance 4000, you complete only the following minimum partitioning steps. 8.

Replacing a Failed Mirrored Disk
The following procedure pertains only to drives not protected under
NetRAID.
Drives protected under NetRAID can be replaced using
the normal procedures for replacing a hot swap drive.
Using the
NetRAID Assistant to configure the new drive and rebuild the RAID
set
does not affect the Marathon Array.
An example would be a split site configuration where LPrs are used
for the IOPs.
WARNING
If the failed disk is the
source
of a mirror copy, do not
implement this procedure until completing all precautions
to save data from this disk.
To replace a failed mirrored disk for a mirror set in which the other
mirrored disk is

e:
1.
Acquire a replacement disk that is equal to or larger in size than
the failed disk.
2.
The replacement disk must be of the same SCSI variety as the
failed disk; for example, the old and new disks must both be
narrow or both wide. Ideally, the disks should be the same size.
3.
Shut down the IOP that contains the failed disk.
4.
Remove the failed disk.
5.
Install the replacement disk.
WARNING
Do not modify any SCSI BIOS settings. Your system must
maintain the SCSI BIOS settings selected during initial
Endurance 4000 installation.
6.
Reboot the IOP in Offline Marathon mode.
7.
Using the Windows NT Disk Administrator, partition the
replacement disk as follows:
NOTE
Because this disk will be the
target
of a mirror copy when its
IOP rejoins the Endurance 4000, you complete only the
following minimum partitioning steps.
8.
Create one primary partition and the Marathon partition.
Make
sure the Marathon partition falls at the end of the disk.
It does
not matter whether the partition scheme matches the other IOP.
