Tivoli Storage Manager creates file system-specific control files that
reside in a hidden directory named .SpaceMan on each file
system to which you add space management. These files also reside in
the /etc/adsm/SpaceMan directory that Tivoli Storage Manager
creates when you install the HSM client. The HSM client automatically
excludes these files from space management. User action is not required
to ensure that the files remain on your local file systems. Table 20 describes the file contents of this directory.
File Name | Description |
---|---|
config/dsmmigfstab | File containing space-managed file system names and the space management settings that you selected for each file system. |
config/dsmmigfstab.pid | A lock file for the dsmmigfstab file. |
config/dmiFSGlobalState | Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file
systems only.
Global and HSM-managed file system information. Related to the DMAPI interface. |
config/dmiFSGlobalState.pid | A lock file for the dmiFSGlobalState file. |
ActiveRecallTab | Active recall table. |
When you add space management to your file systems, the HSM client creates control files in a hidden directory named .SpaceMan. Table 21 provides a brief description of objects that are stored in the .SpaceMan directory in each file system to which you add space management. The HSM client requires these objects for processing.
Attention: The HSM client can create other objects in the
.SpaceMan directory during space management
processing. Do not delete or modify the
.SpaceMan directory, its contents, or any of the file
ownerships and permissions.
Table 21. Control Files Stored in the .SpaceMan Directory
Files | Description |
---|---|
orphan.stubs | Records the names of any files for which a stub file exists on your local file system, but a corresponding migrated file does not exist in Tivoli Storage Manager storage. |
status | Records space management-related statistics for your file system. |
premigrdb.dir premigrdb.pag | Valid for AIX JFS file systems only
Stores the premigrated files database that contains information about each premigrated file. |
dmiFSState | Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file
systems only
Stores information about the file system. |
logdir/ | Records information during file migration or recall. It uses this information to complete any interrupted transactions, such as a system failure. |
SDR/ | Valid for AIX (IBM Regatta pSeries 690)
Stores information for failover that must be shared between cluster nodes that are configured as failover nodes. The directory exists in only one of the .SpaceMan directories of HSM-managed file systems. |
reserved/ | Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file
systems only
Contains reserved files for demand migration. |
