multiple scsi device

[Timothy Phan]

Hi,

  I hope that I'm sending this problem to the right group.  Is there
  some limitation or restriction on connect multiple scsi
  devices and lenght of the scsi cable onto the adaptec?

  I'm currently have 2 internal harddrive, an internal
  CDROM, and 2 external harddrive (total of 5) connected to the
  adaptec control.  Everything is recognized by the
  control in Linux without any problem.  In the last
  few days,  I've tried to add one addition external
  harddrive (to make it 6 in total) and it is not being
  recognized.

  If I removed one of the other, then it would be ok.
  I've check the SCSI ID for each and they all have
  its own uniq ID.  All the cable I used seem to be OK because
  if it is hooked up individually, then no problem.
  Each of the external cable is about 2 feet in length  and
  the internal cable has 7 connector and I do not remember
  its length.

  Thanks.
