Re: hardware needed to install HACMP?

This was on an old 570.

I tracked down an old 2G 9076 SP internal disk. Reset SCSI-id to something
not on the bus. Connected the drive to the internal ribbon in the 570 ,and
brought everything back up. Be careful with the differential/single-ended
disk issue. This is pertinent to both the disk and adapter.

Many thanks.
