LUNs, and you want to operate in HP NetRAID mode, you must
connect the device to a SCSI controller accessory board.
∗ If integrated HP NetRAID is enabled and you plan to use a tape
backup device, you must connect the device to a SCSI controller
accessory board.
HP NetRAID Channels
The integrated HP NetRAID controller refers to channels as 0 and 1.
l For HP NetServer LH 3/3r and LH 4/4r, if only one HP NetRAID channel
is enabled, it becomes Channel 0. If both HP NetRAID channels are
enabled, then SCSI A is Channel 0 and SCSI B is Channel 1.
NOTE For HP NetServer LH 3/3r and LH 4/4r if you enable
HP NetRAID on only one channel, it is recommended that you
use the default configuration and enable HP NetRAID on
SCSI A.
If you enable HP NetRAID on only one channel and later want
to enable a second channel, follow the instructions in
Chapter 9, "For HP NetServer LH 3/3r and LH 4/4r,
Configuring a Second Channel," in this guide.
• For HP NetServer LH 3000/3000r, LH 6000/6000r, and LT 6000r, SCSI
A and SCSI B both operate in the same mode, both as RAID (HP
NetRAID) or both as non-RAID (LVD SCSI).
Record the SCSI ID number and physical capacity of each hot-swap drive in the
correct channel on Worksheet A. Physical drives on different channels can be
assigned to the same array.
NOTE For HP NetServer LH 3/3r and LH 4/4r, if you plan to enable
HP NetRAID on SCSI B, and if you have installed non-hot-
swap SCSI devices, make certain the non-hot-swap and the
hot-swap devices do not share the same SCSI ID. Resolve
conflicts by resetting the SCSI address switch of the non-hot-
swap device.
