1. The minimum operating system is Solaris 2.3.
2. The DWIS/S supports up to 15 targets on the SCSI bus.
3. Do NOT mix narrow (8-bit) and wide (16-bit) SCSI devices on the same controller under Solaris 2.3. Install Patch 101378-01.
4. Warning messages are displayed if fast/wide SCSI is enabled under Solaris 2.3. Install Patch 101378-01.
5. Set scsi_options=0x3f8 in /etc/system to enable fast/wide transfers.
6. The 2.1GB Disk Drive requires 0420 Firmware (370-1412-03) for optimal performance. Set scsi_options=0xf8 in the /etc/system file if older disk drive firmware is used.
7. Install SunSwift in Slot 0 and DWIS/S in Slot 1 when installing SunSwift and DWIS/S on an E10000 I/O board. Refer to BugIDs 4046986, 4049704, and 4091053.
