Power Verification and Addressing
UltraSCSI RAID Enclosure 4–7
Setting the Enclosure Address
The PVA SCSI ID switch establishes the SCSI bus address (device
ID) for all disk drive SBBs in the enclosure. Table 4–2 identifies how
to set the PVA SCSI ID switch setting for each enclosure.
The following restrictions apply to establishing an enclosure address:
• The master enclosure address is always 0.
• There is only one master enclosure in any subsystem.
• No two enclosures in a subsystem are allowed to have the same
address.
See Table 4–3 for the Compaq-supported enclosure addresses.
Caution
All devices on the same SCSI bus must have a unique SCSI
bus ID.
To preclude SCSI bus addressing conflicts, Compaq only
supports PVA SCSI ID switch settings of 0, 2, and 3.
If the PVA SCSI ID switch setting is changed for an
enclosure, the controllers must be RESET to recognize the
new setting.
Table 4–2 Setting the Enclosure Configuration
To decrease the configuration number:
Press the upper switch (C
ALLOUT 1) to step the
address down one address at a time (decrement).
To increase the configuration number:
Press the lower switch (C
ALLOUT 2) to step the
address up one address at a time (increment).
