Multi-initiator configurations are not supported.
The Plug N Play SCAM Support option is not supported.
Ensure that the Adaptec SCSISelect BIOS option Reset SCSI Bus at IC Initialization (under the Advanced Configuration Options menu) is set to Enabled. Run the SCSISelect utility by pressing Ctrl-A when you see the Adaptec banner during system boot.
Reboot the system after you install patches.
If you are both upgrading your Solaris Intel Platform Edition installation and adding a new device driver, you must first upgrade Solaris, then reboot your system, and then apply the Driver Update (DU), as follows.
Perform the Solaris upgrade. Do not apply the cadp DU at this time.
Reboot your system.
When the system has rebooted successfully, insert the DU diskette into the diskette drive and apply the DU as follows.
Mount the DOS formatted file system:
# mount -Fpcfs /dev/diskette0 /mnt |
Change directories:
# cd /mnt/DU/sol_27/i86pc/Tools |
Install the DU:
# . ./install.sh -i |
Perform a reconfiguration reboot.
If you experience problems when using a narrow SCSI CD-ROM drive on the internal wide interface, disable "negotiate wide," "negotiate sync," or both for that device in the Adaptec configuration utility.
If you experience problems when using the narrow internal connector, then disable "de-selection" in the Adaptec configuration utility.
The Fujitsu narrow disk (M1603SAU) has been observed reselecting with an invalid queue tag ID. This is a violation of the SCSI protocol and it causes the cadp driver to behave erroneously. Because this is difficult to guard against, it is best to disable tagged queuing for these targets.
Use the iostat -E command to determine if you have a Fujitsu M1603S-512 disk. If you do, edit the /kernel/drv/cadp.conf file and add the property target n -scsi -options=0x1f78, where n is the target number.
The IBM external wide disk (DFHSS2W, Revision 1717) is not supported.
Using the Adaptec configuration utility:
Configure each SCSI device to have a unique SCSI ID. On the Advanced Configuration Options menu, set Plug N Play SCAM Support to Disabled.
Ensure that devices on either end of the SCSI chain are terminated. When mixing wide (16 bits) and narrow (8 bits) devices on the same wide chain, ensure that a wide device is at the end of the chain. If a narrow device is placed at the end of the chain, the wide devices on the same chain only have the low byte terminated, and this is an illegal configuration.
If there is more than one controller (or an embedded controller), try to use one IRQ per controller.
Enable bus mastering for the slot(s) with your host bus adapter(s), when asked.
For older disk drives, tape drives, and most CD-ROM devices, make sure the maximum SCSI data transfer speed is set to 5.0 Mbps.
Enable support for disks larger than 1 Gbyte if applicable.

LSI Logic (formerly Symbios Logic or NCR) 53C810, 53C810A, 53C815, 53C820, 53C825, 53C825A, 53C860, 53C875, 53C875J, 53C876, 53C895 |
Bus Type: |

Because the NCR BIOS and the Solaris fdisk program may be incompatible, use the DOS version of FDISK (or equivalent utility) to create an entry in the FDISK partition table before installing the Solaris software. Create at least a 1-cylinder DOS partition starting at cylinder 0. If the DOS partition isn't created, the system won't reboot after Solaris installation.
An add-in card with the 53C815, 53C820, 53C825, or 53C825A controller can only be used in a bus-mastering PCI slot. On motherboards with only two PCI slots, both of the PCI slots are usually bus-master capable. On motherboards with three or more PCI slots, and on motherboards with several embedded PCI controllers, some of the PCI slots may not be bus-master capable.
Some PCI motherboards with the LSI Logic SDMS BIOS and an embedded 53C810 or 53C810A controller do not work correctly with the 53C82x family of add-in cards that also have an LSI Logic SDMS BIOS. Upgrading the motherboard BIOS, the add-in card, or both may prevent these conflicts.
On some early PCI systems with the 53C810 chip on the motherboard, the interrupt pin on the chip is not connected. Such a system cannot be used with Solaris software.
Do not attempt to connect wide targets to the narrow connector of the cards listed as supporting narrow disks. These configurations are not supported.
If your adapter supports the LSI Logic SCSI Configuration utility, which can be accessed by pressing Control-C, do not change the value of the Host SCSI ID (an option under the Adapter Setup menu) to anything but 7.
If you experience problems with old target devices, add the following entry to the /kernel/drv/ncrs.conf file:
targetN-scsi-options = 0x0; |
where N is the ID of the failing target.
If you are using a Conner 10805 narrow SCSI drive, you might see warnings like:
WARNING: /pci@0,0/pci1000,f@d(ncrs0): invalid reselection(0,0) WARNING: /pci@0,0/pci1000,f@d/sd@0,0(sd0): SCSI transport failed: 'reset: retrying command' |
You can suppress these warnings by disabling tagged queuing in the ncrs.conf file. See the ncrs(7D) man page.
On some Pentium motherboards (Intel NX chipset) using P90 or slower processors, ncrs hangs and this message is displayed on the console:
WARNING: /pci@0,0/pci1000,3@6(ncrs0) Unexpected DMA state:active dstat=c0<DMA-FIFO-empty, master-data-parity-error> |
This is an unrecoverable state; the system will not install using the ncrs driver.
The ncrs driver supports Revision 4 and above of the 53C875 chipset. Previous revisions were pre-release versions of the chip, so there might still be a few in circulation.
In rare circumstances, when using an SDT7000/SDT9000 tape drive, you see this message on the console:
Unexpected DMA state: ACTIVE. dstat=81<DMA-FIFO-empty,illegal-instruction> |
In these instances, the system recovers and the tape drive remains usable. You can still use the tar command to add or extract files to or from the tape in the drive.
