____________________ Note _____________________

Do not use PVA ID 1:

With Port-Target-LUN (PTL) addressing, the PVA ID is used to determine the target ID of the devices on ports 1 through 6 (the LUN is always zero). Valid target ID numbers are 0 through 15, excluding numbers 4 through 7. Target IDs 6 and 7 are reserved for the controller pair, and target IDs 4 and 5 are never used.

The enclosure with PVA ID 0 will contain devices with target IDs 0 through 3; with PVA ID 2, target IDs 8 through 11; with PVA ID 3, target IDs 12 through 15. Setting a PVA ID of an enclosure to 1 would set target IDs to 4 through 7, generating a conflict with the target IDs of the controllers.

5.Remove the program card ESD cover and insert the controller’s program card. Replace the ESD cover.

6.Install disks into storage shelves.

7.Connect a terminal to the maintenance port on one of the HSG80 controllers. You need a local connection to configure the controller for the first time. The maintenance port supports serial communication with the following default values:

•9600 BPS

•8 data bits

•1 stop bit

•No parity

8.Connect the RA8000 or ESA12000 to the power source and apply power.

____________________ Note _____________________

The KGPSA host bus adapters must be cabled to the switch, with the system power applied before you turn power on to the RA8000/ESA12000, in order for the HSG80 to see the connection to the KGPSAs.

9.If an uninterruptible power supply (UPS) is used instead of the external cache battery, to prevent the controller from periodically checking the cache batteries after power is applied, enter the following command:
