can't add more than 8 physical disk to an array

power vault 210S. Running off of a perc 2/dc.
 
the power vault has 13 external disks. But I can't get more than 8 of them to be added to an array. updated the firmware, still no luck. all disks are the same: 70GB SCSI -3.
 
any advice would be great!

Re: can't add more than 8 physical disk to an array

Saw a similar problem several years back.  Check to see what speed your drives are negotiating at (can be seen at boot time with most controllers).   If you see the speed going down as the ID gets higher then it could be a cable problem or lack of SCSI termination.  In my case it was the cable.

Good luck in debugging this.

thanks for the input. looked up info on the raid controller. seems that it doesn't support more than 8 disks per channel. cheap!

Not necessarily cheap considering the age of the controller. 8 physical drives per logical drive was the standard back in the late 90's when that controller was released.

You could use up to 16 drives using RAID 10 or 50.
