Creating disk groups

The new disks you add will typically be used to create new disk groups. Although you cannot
select which disks will be part of a disk group, you can control this by building the disk groups
sequentially.
Add the disk drives required for the first disk group, and then create a disk group using these disk
drives. Now add the disk drives for the second disk group, and then create that disk group. This
process gives you control over which disk drives are included in each disk group.
NOTE: Standard and FATA disk drives must be in separate disk groups. Disk drives of different
capacities and spindle speeds can be included in the same disk group, but you may want to
consider separating them into separate disk groups.

Handling fiber optic cables

This section provides protection and cleaning methods for fiber optic connectors.
Contamination of the fiber optic connectors on either a transceiver or a cable connector can impede
the transmission of data. Therefore, protecting the connector tips against contamination or damage
is imperative. The tips can be contaminated by touching them, by dust, or by debris. They can be
damaged when dropped. To protect the connectors against contamination or damage, use the
dust covers or dust caps provided by the manufacturer. These covers are removed during installation,
and are installed whenever the transceivers or cables are disconnected. Cleaning the connectors
should remove contamination.
The transceiver dust caps protect the transceivers from contamination. Do not discard the dust
covers.
CAUTION:
whenever a transceiver or a fiber cable is disconnected. Remove the dust covers or dust caps from
transceivers or fiber cable connectors only when they are connected. Do not discard the dust covers.
To minimize the risk of contamination or damage, do the following:
Dust covers — Remove and set aside the dust covers and dust caps when installing an I/O
module, a transceiver or a cable. Install the dust covers when disconnecting a transceiver or
cable.
When to clean — If a connector may be contaminated, or if a connector has not been protected
by a dust cover for an extended period of time, clean it.
How to clean:
1. Wipe the connector with a lint-free tissue soaked with 100% isopropyl alcohol.
2. Wipe the connector with a dry, lint-free tissue.
3. Dry the connector with moisture-free compressed air.
