2 Maintaining Drives
You can replace a failed drive while the array remains running.
About Drive Types
Depending on your configuration, your array supports up to 24 2.5-inch SAS drives or up to 12 3.5-inch SAS
drives in internal drive bays.
Drives are connected to a backplane through drive carriers and are hot-swappable.
Drives are supplied in a carrier that is keyed to fit into specific array models, and cannot be installed in other
Dell arrays, or arrays not from Dell Inc.
Identifying Failed Drives
A drive failure is indicated by:
•
LEDs on the drive. See
•
A message on the console, in the event log, or in the Group Manager Alarms panel.
•
Indications in the Group Manager Member Disks window or the CLI
output.
Behind the bezel, arrays have a label showing the drive numbering for that specific array model:
•
In arrays with 2.5-inch drives (installed vertically in a row), the drives are numbered 0-23, left to right.
•
In arrays with 3.5-inch drives (installed horizontally), the drives are numbered from left to right and top to
bottom, starting with 0 on the upper left side.
