Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients
You can recall a migrated file to your local file system from storage using
either transparent recall or selective recall.
Transparent recall automatically returns a migrated file to your
local file system when you access the file. If you change the recall
mode for a migrated file, or for a specific execution of a command, you change
how the HSM client recalls a migrated file.
- Note:
- The following transparent recall modes, available in read access, are for AIX
JFS file systems only.
- Migrate-on-close
- Temporarily recalls a migrated file to its originating file system.
The recalled file remains on your local file system only for as long as it is
open. When you close the unmodified file, a stub file replaces it on
your local file system. The file is migrated again. It is not
necessary to send a copy of the file to storage because you did not modify the
file. The copy that currently resides in storage remains valid.
- Normal
- Recalls a migrated file to its originating file system. The
recalled file remains on your local file system. When you close the
unmodified file, the copy that currently resides in storage remains
valid. The local copy is premigrated.
- Read-without-recall
- Reads a migrated file from storage without storing it on your local file
system. The HSM client reads information sequentially from the migrated
file, and caches information that it reads from the file into a memory buffer
on your workstation. The read-without-recall mode is intended for
single-access, sequential reads of non-executable files.
Selective recall returns specific, migrated files to your local
file system. You select the files that you want to recall. You,
as root user, can selectively recall any migrated file from your
workstation. When you selectively recall a file, you store it in its
originating file system. Selective recall overrides the recall mode
that you set for a migrated file.
