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 When replacing a disk that is incorporated into a disk. 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 If you make an error in the following steps, it is likely other IOP is independently capable that the IOP on which you are replacing a failed disk of sustaining the server, including the will be removed. CE operating system and connections to the redirected networks: • From the application task bar, select Start Programs Marathon Endurance Endurance Manager. Refer to Chapter 4 for detailed information about how to run and use the 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).
