Dskana Options - Alpha Microsystems AM-6000 Owner's Manual

Page 5-10
Use DSKANA frequently on all of your disks. It is a good practice to use DSKANA on every disk just
before you back up the files on that disk.
For more information on DSKANA, see the System Commands Reference Manual.
NEVER use DSKANA (unless you are using the /C option described below) while other users
are accessing the specified disk; doing so may damage the bitmap and the files on the disk.
To use DSKANA, follow these steps:
1. Log into OPR: by typing:
LOG OPR:
2. Type DSKANA followed by the device name of the disk you want to analyze and press
For example, to analyze DSK1:, type:
DSKANA DSK1:
You now see:
[Begin analysis of DSK1:]
As DSKANA checks the disk, it displays the disk account numbers. When it finishes, it displays
the results of its analysis. For example:
DSKANA DSK1:
[Begin analysis of DSK1:]
[1,2]
.
[100,20]
[The following blocks were marked in use but not in a file]
1767
[The following blocks were in a file but not marked in use]
[Rewriting BITMAP]
No file errors
If you see the "No file errors" message, the file structure on the disk is intact. If DSKANA lists a
number of file errors, there is a problem with the disk's file structure. Your next step is to run DSKANA
again, using either the /L or /E option—discussed below—to see where the errors are on the disk.
For the complete procedure to follow if DSKANA finds any file errors, see "Recovering From Disk
Errors" in the System Operator's Guide.
