General Troubleshooting Information
Keep the following points in mind when troubleshooting disk problems.
1.
Do not save translations or announcements on the disk if unresolved Disk
Drive or Host Adapter problems are present.
If there is something wrong with the MSS, any attempt to save translations
or announcements could destroy a good copy of the files on disk.
2. When multiple error conditions are present, check for Host Adapter and
Tape errors first.
Maintenance software cannot always distinguish between errors caused
by the Disk Drive, and errors caused by the Host Adapter or Tape Drive.
