i. Reinstall trim.
– Install the 1/2 U filler panel (part number A3661-00003) to the bottom of the disk array's front bezel using four
of the screws (part number 2680-0273) from the hardware mounting kit.
– Reinstall the disk array's front bezel.
– Reinstall any trim removed from the cabinet and close the cabinet doors. Do not power up the cabinet at this
time.
5. Set the Fibre Channel ID for the SP in the Disk Array
Each HP Model 30/FC High Availability Disk Array can have two SPs (storage processor controllers), which are located
in the back of the disk array. In a basic cluster consisting of two HP NetServers, one HP FC-AL hub and one disk array,
the HP FC-AL hub will be connected to SP A of the disk array. SP A is on the left of the Fibre Channel Interconnect
PCA (Printed Circuit Assembly). The SP on the right, if it is present, is SP B.
The back of the disk array has two pairs of Fibre Channel address switches on the Fibre Channel Interconnect printed
circuit assembly (PCA) (see figure 20). One pair is used to set the Fibre Channel address for SP A. The other pair sets
the Fibre Channel address for SP B. The left switch in each pair has eight values (hexadecimal 0x0 through 0x7); the
right switch has 16 values (hexadecimal 0x0 through 0xF).
The Fibre Channel address is composed of two digits. The left digit (the high-order digit) is set by the left switch. The
right digit (the low-order digit) is set by the right switch.
Occasionally two or more ports in an FC arbitrated loop will arbitrate simultaneously. Priorities are decided according to
the loop IDs. The higher the loop ID, the higher the priority.
NOTE
Using table 2 as a guide, set the switches for the SP's Fibre Channel address. Each Fibre Channel address should be set
to a unique value. For example, if the desired loop ID is 0x09, the left switch is set to 0 and the right switch is set to 9.
Valid loop IDs are from 0x00 to 0x7E (126 decimal) inclusive.

Each SP requires a unique Fibre Channel address number.
Do NOT use FC address 0x7E (126 decimal) because it will cause a system panic.
