The Plug N Play SCAM Support option is not supported.
If the BIOS is enabled on the card, 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.
If the adapter is being used in a multi-initiator configuration:
Ensure that the system boot disk is not on the shared (clustered) bus.
Set the Reset SCSI Bus at IC Initialization option to Disabled.
Set the Host Adapter BIOS option (under the Advanced Configuration Options menu) to Disabled:Not scan.
Edit the /kernel/drv/cadp.conf file and add the property:
Reboot the system after you install patches.

Known Problems and Limitations
The cfgadm(1M)replace_device command is unreliable when used to replace a disk attached to an HBA controlled by the cadp(7D) driver.
To replace such a disk, use the cfgadm remove_device command followed by a cfgadm insert_device command, for example:
The cadp.bef realmode driver only supports 10 adapters at boot time. Therefore, ensure that the boot disk is attached to one of the first 10 adapters. Note that all targets will be available for installation and use by the Solaris cadp (protected mode) driver.
Running the format(1M) command on a Seagate ST19171W 9 GB disk drive fails.
Some motherboards have problems supporting channel B with boards based on the Adaptec AIC-7895 chip, such as the AHA-2940U Dual and the AHA-2940UW Dual series. The problem arises because the BIOS doesn't properly assign two interrupts for PCI interrupts INTA and INTB on the slot containing the AIC-7895 chip. This causes devices connected to channel B to fail, and messages about timeouts and resets on those devices to appear on the console.
For example, this problem occurs on the Intel PR440FX (Providence) dual Pentium Pro motherboard, with BIOS revisions up to and including 1.00.08.DI0. For that motherboard, a workaround is to set the 'Advanced/PCI IRQ Mapping' feature to 'To ISA Legacy IRQs.' A similar workaround might apply to other motherboards with problems supporting channel B.
Another possible workaround is noted on Adaptec's Web site at http://www.adaptec.com/support/faqs/aha394x.html.
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.
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 targetn-scsi-options=0x1f78, where n is the target number.
The IBM external wide disk (DFHSS2W, Revision 1717) is not supported.
When setting up a SCSI bus configuration, avoid connecting wide devices to a narrow bus. However, if you have such a configuration, add the following entry to the cadp.conf file:
where n is the target ID of the wide device on the narrow bus. This entry disables wide negotiation for the specified target. Also ensure that the upper 8 bits of the bus are properly terminated at both ends of the SCSI chain.
If you experience installation problems on systems with Intel 440BX/440GX motherboards, upgrade the motherboard BIOS with the latest revision.

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.
Enable support for disks larger than 1 Gbyte if applicable.
