PS5000 Hardware Maintenance
Installing Disks
Before installing a disk or blank carrier in a PS5000 array, attach an electrostatic
protection device, as described in Using an Electrostatic Wrist Strap on page 1-4.
Notes: Install only disks of the same type, speed, and spin rate in an array. The
color of the handle release button indicates the disk type (black for SAS;
gray for SATA).
SAS disks require the Type 4 control module. SATA disks require the
Type 5 control module.
You can use disks with different sizes in an array. However, the smallest
disk in the array will determine how much space can be used on each disk.
For example, if the smallest disk is 400GB, only 400GB of space will be
available for use on each disk.
Be sure to insert a disk fully in the chassis before pushing in the handle.
When correctly installed, the disk carrier should not protrude from the
chassis. After installation, make sure the disk power LED (top) is green or
flashing green.
There is a two-minute delay between the time you insert a disk and the
time the disk is automatically configured into a RAIDset. This time
interval allows multiple disks to be simultaneously configured in an array,
which is more efficient than installing a single disk, configuring it, and
then repeating the process. For example, when you install a disk, the timer
starts. If no other disks are installed, the disk is configured after a delay of
two minutes. If you install another disk before two minutes have elapsed,
the timer is restarted.
If you install a disk during RAID reconstruction or verification, the new
disk will not be configured until the operation completes.
Make sure the disk is oriented in the position shown below, with the
handle release button to the left.
When correctly installed, a disk will be level with the front of the array. If
the disk is protruding from the array, reinstall the disk.
Figure 2-4 shows how to install a disk in an array. Use the same instructions for
installing a blank carrier.
