Troubleshooting Problem 11 The Adaptec SCSI RAID controller I2O BIOS reports the drive as a disk instead of a drive. Solution 11 This typically happens when a drive that is attached to an Adaptec SCSI RAID controller has been formatted with a sector size other than 512 bytes. Use SMOR to reformat the drive with 512-byte sectors. This can also occur if the drive is the 9th or higher logical drive attached to the controller. IMPORTANT: Using SMOR to set Bootable Devices to Disabled as in the previous problem will result in the same symptoms. If you require access to disk drives connected to the Adaptec SCSI RAID controller during the boot process, change Bootable Devices to Normal. Problem 12 Although the SCSI devices can be accessed by the Adaptec SCSI RAID controller, the fault LEDs on the devices in a RAIDstation storage cabinet do not flash during boot-up and the Adaptec SCSI RAID controller does not detect drive swaps or cabinet failures. Solution 12 These symptoms indicate that the RAIDstation storage cabinet status signals are not being properly received by the Adaptec SCSI RAID controller. For SAF-TE or SES: this can result from a failed enclosure monitoring module in the subsystem cabinet. HP 2100S SCSI RAID Controller User Guide C-7

Troubleshooting

Problem 11

The Adaptec SCSI RAID controller

BIOS reports the drive as a disk instead of a

drive.

Solution 11

This typically happens when a drive that is attached to an Adaptec SCSI RAID

controller has been formatted with a sector size other than 512 bytes. Use SMOR to

reformat the drive with 512-byte sectors. This can also occur if the drive is the 9th or

higher logical drive attached to the controller.

IMPORTANT:

Using SMOR to set Bootable Devices to Disabled as in the previous problem

will result in the same symptoms. If you require access to disk drives connected to the Adaptec

SCSI RAID controller during the boot process, change Bootable Devices to Normal.

Problem 12

Although the SCSI devices can be accessed by the Adaptec SCSI RAID controller,

the fault LEDs on the devices in a RAIDstation storage cabinet do not flash during

boot-up and the Adaptec SCSI RAID controller does not detect drive swaps or

cabinet failures.

Solution 12

These symptoms indicate that the RAIDstation storage cabinet status signals are not

being properly received by the Adaptec SCSI RAID controller.

For SAF-TE or SES: this can result from a failed enclosure monitoring module in the

subsystem cabinet.
