Power Verification and Addressing (PVA)
4–6 UltraSCSI RAID Enclosure
Setting the Enclosure Address
Use the procedure in Table 4–2 to identify the enclosure as either a master
or an expansion enclosure. This switch also establishes the SCSI bus address
(device ID) for the disk drives (SBBs) in the enclosure. The following
restrictions apply to establishing the enclosure address:
1. The master enclosure address is always 0.
2. There is only one master enclosure in any subsystem.
3. No two enclosures can have the same address.
See Table 4–3 for the DIGITAL-supported enclosure addresses.
____________________ Caution ____________________
DIGITAL does not support any combination of enclosure
address settings that assign the same SCSI bus device address to
more than one device on a SCSI bus
To preclude SCSI bus addressing conflicts, DIGITAL only
supports enclosure address settings 0, 2, and 3.
