Other Documents You May Need
Dell continues to offer new types of connectivity modules for your system and provides
documentation on how to set up and use them. The documentation for a particular module is
included with the module product or is available at
support.dell.com
.
NOTE: Ensure that you also refer to support.dell.com for any updates to the documentation that you
received with your module.
300-GB Hard Drive Synchronizing and Rebuilding Durations
Because of the large disc size of 300-GB hard drives, expect longer synchronizing and rebuilding
durations than smaller hard-drive disc sizes. A 300-GB hard drive installed in a system with very low
or no I/O activity requires at least 22 hours to synchronize or rebuild. A 300-GB hard drive installed
in a system with high I/O activity requires up to 51 hours to synchronize or rebuild.
Complete Hard Drive Synchronization Before Cold-Swapping
the Hard Drive
If you install and start the synchronization of a hard drive, ensure that you allow the
synchronization to complete. Otherwise, if that hard drive is cold-swapped into another RAID or a
non-RAID system, the hard drive will not be recognized.
NOTE: A hard drive that has not completed synchronization can be hot-swapped into another RAID or
non-RAID system without any recognition problems.

An I/O module's green system/diagnostic indicator is off when the module is properly operating or
is off and blinks when the module is not properly operating. See "Indicators, Codes, and Messages"
in your
