Stop Internal Disk Drives
The following procedure identifies the active processes that are currently using an
internal disk. This procedure might not generate a complete list of dependent
processes.
Stop Internal Disk Drives
In each enclosure you remove, you stop all internal disk drives that are not already
down.
1. At the SCF prompt, enter
-> STOP DISK (diskname1, [ , disknamen ]... )
You see a display similar to:
2. Enter
Y.
If this disk contains open files, you receive a message similar to:
In this example, $DATA03 has two open files.
•
If you enter Y, you terminate access to the disk. Results in this case are
system-dependent and might be unpredictable.
•
If you enter N, you can then analyze what process is accessing this disk and
take appropriate action. Consult your system analyst and your service provider.
Step Action Result
1. At the TACL prompt, enter this command for each
disk volume listed on Worksheet 8:
> FUP LISTOPENS diskname.*.*
For example, for the disk volume $OSS:
> FUP LISTOPENS $OSS.*.*
You receive a list of
processes that currently
have files open on the
specified disk.
2. Record this information in the critical processes box on Worksheet 8.
3. For each process in the list, either terminate (that is, stop and delete) the process
or copy the file it has open to a disk drive in an enclosure that will not be
removed.
4. If you moved this file, reconfigure the process to open the copied file.
5. Repeat this procedure for each internal disk drive in the enclosure to be
removed.
-> STOP DISK ($DATA01, $DATA02, $DATA03)
STORAGE W01007 The STOP DISK \TROLL.$DATA01 operation will cause
\TROLL.$DATA01 to be INACCESSIBLE to user processes.
Do you want to STOP DISK \TROLL.$DATA01 (Y/[N])
STORAGE W01008 DISK \TROLL.$DATA03 contains 2 open files.
Are you sure you want to STOP DISK $DATA03 (Y/[N])
