4.1 Basic Problems
If the system cannot work with the adapter, check the following:
Is CMOS setup required to enable PCI bus parameters
Is the adapter installed in a bus-master PCI slot
Are all the cables connected correctly
Does the configuration follow the SSA rules for this adapter
If the system cannot access the SSA disk drives, check the following:
Is power turned on to the disk drives
Has the configuration utility been run for all the required disk drives, and do they appear in the list of attached resources
Are the disk drives connected in a loop, either from SSA loop A port 1 to SSA loop A port 2, or from SSA loop B port 1 to SSA
loop B port 2?
Is the light next to the adapter-loop ports on, showing that both ports are operational
If the system fails to boot from an SSA disk drive, check the following:
That there is
not
an IDE disk drive installed
That there is
not
a SCSI adapter with BIOS enabled installed in a higher-priority PCI slot than the SSA adapter
That the CBIOS enable
That the SSA device drivers are loaded before the SCSI device driver
That the address (drive letter) of the partition from which you are trying to boot has not changed. (Adding extra drives can cause
the addresses of existing drives to be changed.)
