Recovering from Hard Drive Failure
87MSA1000 Reference Guide
Moving Array Controller Drives and Arrays
Caution: Back up all data before removing drives or changing configurations.
Failure to do so could result in permanent loss of data. Before moving drives
and arrays, run the Array Configuration Utility.
Drives can be moved to other ID positions on the same array controller. You may
also move a complete array from one controller to another, even if the Controllers
are on different servers. Arrays on different Controllers can also be moved to
another controller.
Before moving drives, these conditions must be met:
■ No drives are failed, missing, or degraded.
■ The move will not result in more than 14 physical drives in the MSA1000 or
42 in a single enclosure.
■ No more than 32 logical volumes will be configured for a controller.
■ The array should be in its original configuration with no active spare drives.
■ Capacity expansion is not running.
■ Controller firmware is the latest version (recommended).
Before moving an array from one controller to another, these additional conditions
must be met:
■ All drives in the array must be moved at the same time.
■ Positions of drives on the destination controller should not be changed during
relocation of the array.
When the appropriate conditions are met, follow this procedure:
1. Power OFF the system.
2. Move the drives.
3. Power the system ON.
A #86 front-panel display message should be displayed, indicating that drive
positions were changed and the configuration was updated. If a #121 front-panel
display (no volumes) message is displayed, turn the system OFF immediately to
avoid data loss, and return the drives to their original locations.
You can now check the new drive configuration by running the Array
Configuration Utility.
