Notes
- Remove the terminators from the underside of the drive.
- Terminate the Sun386i with external terminator 530-1381.
- Sun-3/470, Sun-4/370, and Sun-4/470 systems with dual option trays are
terminated internally on the 501-1493 Interface PCB. The left side tray must be
installed to terminate the SCSI bus.
- Sun-4/370 and Sun-4/470 systems with a single option tray are terminated
externally with terminator 150-1346.
- Terminate the External Storage Module with terminators 530-1381 or
150-1785.
- Terminate the Sun-4/330 on the SCSI-Out PCB with three 220/330 terminators,
120-1608-01.
Format Utility Notes
- The 94171-327 has fewer cylinders than the 94171-344.
- The SunOS 4.x format utility fails if the 94171-327 is used with
the standard format.dat entry on any system other than a Sun386i.
- Use the following format.dat entry for the 94171-327 on SunOS 4.x.
disk_type = "CDC Wren IV 94171-327" \
: ctlr = SCSI : fmt_time = 4 : cache = 0x11: trks_zone = 9 \
: asect = 3 : ncyl = 1520 : acyl = 2 : pcyl = 1549 : nhead = 9 \
: nsect = 46 : rpm = 3600 : bpt = 20833
- Solaris 2.x includes an entry for the 94171-327 in format.dat.
Remove the comment symbol "#" to use the entry.
