Replacing a Failed Mirrored Disk

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.

Often disks can be replaced within a RAID subsystem with no need for special Endurance
considerations at all. Refer to your vendor’s RAID documentation and ignore this procedure.

Caution:

Before proceeding, make sure you are properly grounded

using,

for instance, a wrist strap with an attached alligator clip that is
connected to an appropriate ground.

To replace a failed mirrored disk for a mirror set (with no hardware RAID) and in which the
other mirrored disk is

active

, follow this procedure:

Step

Action

Notes

1

Acquire an appropriate replacement
disk.

When replacing a disk that is incorporated into a
hardware RAID set with local IOP hardware
redundancy, comply with the RAID controller
vendor’s requirements.
When replacing a disk that was configured using no
hardware RAID (RAID 0), the replacement disk must
be the same size or larger than the failed disk being
replaced: the same size or larger than the

other

member of the

same

mirror set on the

other

IOP.

2

Before proceeding, verify that the

other

IOP is independently capable

of sustaining the server, including the
CE operating system and
connections to the redirected
networks:
• From the application task bar,

select

Start

Programs

Marathon

Endurance

Endurance Manager

.

• Verify that the IOP is

online

(bright

green).

• Verify that all disks on the other

IOP are

online

(bright green).

• Verify that all network connections

on the other IOP are

online

(bright

green) or in

standby

(dark green).

If you make an error in the following steps, it is likely
that the IOP on which you are replacing a failed disk
will be removed.

Refer to

Chapter 4

for detailed information about

how to run and use the Endurance Manager.
