You can update firmware using RAIDar or using FTP (File Transfer Protocol). See the AssuredSAN 3000
Series RAIDar User Guide for more information.
Replacing a disk drive module
A disk drive module consists of a disk in a sled. Disk drive modules are hot-swappable, which means they
can be replaced without halting I/O to the vdisks, or powering off the enclosure. The new disk drive
module must be of the same type, and possess capacity equal to or greater than the one being replaced.
Otherwise, the storage system cannot use the new disk to reconstruct the vdisk (see "About vdisks" and
"About disk failure and vdisk reconstruction" topics in the RAIDar user guide).
Air management modules
An air management module looks like a disk drive module; however, it is an empty box — also known as
a blank — used to maintain optimum air flow for proper cooling within an enclosure. Air management
modules are installed in slots missing disk drive modules. If you must remove a disk drive module, but
cannot immediately replace it, you must either leave the faulty module in place, or insert an air
management module in its place.
The blank is installed using the same procedure as
the blank is removed using the same procedures as
Before you begin
CAUTION: Removing either a disk drive module or blank impacts the airflow and cooling ability of the
enclosure. If the internal temperature exceeds acceptable limits, the enclosure may overheat, and
automatically shut down or restart. To avoid potential overheating, wait 20 seconds to allow the internal
disks to stop spinning, then insert the new disk drive module or blank.
See CAUTION bullets regarding "electrostatic discharge" and "anti-static protection" on
Verifying component failure
Before replacing a disk, perform the following steps to ensure that you have correctly identified the module
requiring removal and replacement.
CAUTION: Failure to identify the correct disk drive module could result in data loss if the wrong disk is
removed from the enclosure.
When a disk drive fault occurs, the failed disk's fault indicator LED, located on the enclosure's front panel,
illuminates solid amber (see the AssuredSAN 3000 Series Setup Guide for a description of LEDs and disk
drive slot numbering for your enclosure). You can determine from visual inspection which disk in the
enclosure is experiencing a fault/failure using the fault LED for your disk type.
NOTE: For enclosures equipped with a dust filtration bezel, you must remove the bezel to view the disk
drive LEDs. Enclosure status LEDs are visible on the labeled bezel.
See the enclosure bezel kit installation document in your product ship kit for information about removing
and installing the bezel, or for instructions about servicing or replacing the bezel air filter. Alternatively, you
can observe disk component health using management interfaces to verify component failure or
component operation (see
