Device IDs
Note the following guidelines for each controller or adapter type:
•
For NonStop Himalaya K-series servers:
°
The MFC supports one drive CRU for each controller. This drive CRU must
have a device ID of 5.
°
The 3216 tape controller supports up to two drive CRUs. If one drive CRU is
attached to the 3216 controller, it must have a device ID of 5. If two drive
CRUs are attached to the same 3216 controller and linked by a daisy-chain
cable, the device IDs must be 4 and 5.
•
For NonStop Himalaya S-series servers:
°
The ServerNet addressable controller (SAC), which is part of the PMF CRU or
IOMF CRU, supports one drive CRU. This drive CRU must have a device ID
of 5.
°
The 6760 ServerNet device adapter, connected by either a SCSI cable (S-PIC)
or a fiber-optic cable (F-PIC), can support one tape drive for each PIC. On an
S-PIC, the device ID can be 0 through 5. On an F-PIC, the device ID can be 4
or 5. On either, the default is 5.
See Table 3-3 for a summary of device IDs based on the controller or adapter type.
