You can find more information about SCSI HBA OLA/R restrictions by
going to the HP-IT Resource Center (ITRC), at the following URL:
http://itrc.hp.com
1. Go to the area for knowledge trees
2. Under "Hardware" select Networks
3. Select mass storage connectivity
4. Select scsi hba’s
5. Select technical support
This takes you to a page titled "scsi hba’s." (You might want to
bookmark this page, for future reference.)
6. Select the ola/r support link in the list on the left side of the page; this
takes you to the SCSI HBA OLA/R restrictions.
SCSI PCI HBA Documentation Correction
An error exists in the current manual for each of following SCSI PCI
Host Bus Adapters (HBAs): A4800A, A5149A, A5150A, and A5159A
The content for the “Setting the SCSI IDs” section of the “Installing the
Adapter” chapter is not correct. The correct content for the “Setting the
SCSI IDs” section is as follows:
You must assign the SCSI host bus adapter and each SCSI device a
separate SCSI ID (0 through 15 for a 16-bit SCSI bus). The device's
priority on the SCSI bus is determined by the device's SCSI ID. The
order of SCSI ID priorities (from highest to lowest) is 7, 6, 5, 4, 3, 2,
1, 0, 15, 14, 13, 12, 11, 10, 9, and 8. A device with SCSI ID 7 has
the highest priority, and one with SCSI ID 8 has the lowest.
When you are assigning SCSI IDs, we recommend you give the
SCSI host bus adapter higher priority than the other SCSI devices
on the bus. SCSI ID 7 is the preset SCSI ID for your HP SCSI host
bus adapter (giving it the highest priority on the SCSI bus). Set
each of the other SCSI devices on the bus to one of the remaining
SCSI ID's.
For a multi-initiator (High Availability [HA]) configuration-where
multiple SCSI host bus adapters are connected to the same SCSI
bus-the SCSI host bus adapter that carries the most traffic should
be assigned a SCSI ID of 7 (giving it the highest priority), then you
