OSM User's Guide (G06.27+)

Clear Data
Erases all data on the disk but leaves the disk label intact. Clear Data does not erase the FIR data in
the CE sector, the volume label, the boot sector, or the spare tracks table. After a Clear Data
completes or is cancelled, the disk drive is not usable until you restore the file system by using the
SCF command Alter Label.
Disable Drive Bypass
Opens up the specified port or ports (A and/or B) on the disk drive for use.
Enable Drive Bypass
Shuts down the specified port or ports (A and/or B) on the disk drive.
Firmware Update
Updates firmware for the fibre channel disk drive. This action can be performed only when either
both Primary and Backup paths are in the Down state or when one is Harddown and the other is
Down.
Replace
Displays the procedure for replacing the disk.
Reset Backup Path
Places the backup path in a state from which it can be started.
Reset Disk
Places the disk in a state from which it can be started. This action might be necessary before starting
a disk that has both paths in a Hard Down state; if a hardware error has occurred; if the disk was
stopped with an Abort action; or if a Stop or Abort fails to put the disk into the Down state.
If only one disk path is in a Hard Down state, you can use the Reset Primary Path or Reset Backup
Path as appropriate.
Reset Primary Path
Places the primary path in a state from which it can be started.
Reset Volume
Places the volume in a state from which it can be started.
Responsive Test
Verifies that the disk drive is installed and responding.
