Running the DEVICE EXCERCISOR on Apollo Workstations - An Example

DEX is a "device excercisor" which runs as a standalone utility and is found under the /sauN/... directory. It performs fairly thorough device tests for ESDI disk drives. I'm not sure if it is useful on SCSI drives.

Here is a transcript of a DEX session run on a DSP3500 which is using a WD7000 controller and one Maxtor 380MB disk.

NOTE 1: You can not run DEX on a mounted volume or a volume in use. Instead, shut down the workstation and bring up the standalone version.

NOTE 2: FBS takes a VERY LONG TIME. Something on the order of 4 hours per pass on a 380MB drive. I'd suggest selecting 2 passes and letting it run overnight.

NOTE 3: On older versions of DEX a password is sometimes requested. If this is the case, try one or more of the following responses:
service
service8
domain


With workstation shut down and in service mode
