Explanation:

This driver handles both SCSI-2 disks in the SPARCstorage Array and Fibre Channel Arbitrated Loop (FC-AL) disks on Private loops.

The specific type of each disk is determined by the SCSI inquiry command and reading the volume label stored on block 0 of the drive. The volume label describes the disk geometry and partitioning; it must be present or the disk cannot be mounted by the system.


Therefore, the "i/o to invalid geometry" error is reported by the scsi device driver and is a result of the scsi inquiry command not being able to read the label stored on block 0 of the drive/lun.
