HP-UX Operating System
HP-UX on the V2500/V2600
On multiple-cabinet V2500/V2600 servers, the first component of the
hardware path indicates which cabinet a hardware component resides
upon.
Hardware on cabinet ID 0 is listed with a first hardware path field
starting at 0, hardware on cabinet ID 2 is listed starting at 64, cabinet
ID 4 starts at 128, and cabinet ID 6 starts at 192.
For example, a disk on cabinet ID 0 could have a hardware path of:
1/2/0.9.0
The above disk is on cabinet ID 0, is connected to PCI bus 1, slot 2, and
has a target (SCSI ID) of 9. A disk at the same relative location but on
cabinet ID 2 has a hardware path of:
65/2/0.9.0
The above disk is on cabinet ID 2, and is connected to PCI bus 65, slot 2,
and has a target (SCSI ID) of 9. This corresponds to the top left PCI card
cage of cabinet ID 2, as shown in Table 13.
The following table lists the hardware path numbering for key V2500/
V2600 system components as they are numbered on the various cabinets
in a multiple-cabinet V2500/V2600 server.
