RAIDWatch User’s Manual

shutting down the system (hot-swapping). All EonStor subsystems

support drive hot-swapping.

♦ If the replacement drive is installed on the same channel and ID

(the original drive slot where the faulty drive was), you can then

proceed with data rebuilding.

♦ If the replacement drive is installed on a different channel or ID

(different drive slot) or the periodic drive scan function has been

disabled, you need to scan in the new drive first, and then assign it

as a spare drive of the logical drive which had a drive failure. Data

rebuilding will have to be manually initiated.

IMPORTANT!

Although the RAID system provides uninterrupted disk access even after a

disk failure, do not leave a failed drive unattended. Without replacement,

the system will not survive a second physical drive failure on the same

logical drive (RAID3 and 5). A defective drive must be promptly replaced

and data rebuilt.

CAUTION!

When performing hot-swapping, be sure to remove only the defective

drive. Removing the wrong drive will result in complete, irrecoverable

data loss. Use the Enclosure View window or Logical Drive Information

window to locate exactly which physical drive has failed.

2.5 Before You Start

RAIDWatch Manager comes with password protection that prevents

unauthorized modification of the disk array configuration. During each

attempt at modifying the system configuration, the configuration will

require the correct password before proceeding.

By default, the RAIDWatch Manager station comes with a password for

and other security features, see the Password section of Chapter 7,

Configuration Parameters.
