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 and SSD drives or up to
24 3.5-inch SAS or NL-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.
Dell uses specially qualified and tested hard drives for its EqualLogic storage systems, and manages
hard drive quality and firmware only for those drives. As a result, only Dell-provided hard drives are
supported by PS Series arrays. Attempts to use other, unapproved hard drives in the PS6210 array
will not be successful.
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
command 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.
