ADD FILESET Command
INFO FILESET command might not appear to be the same as the specified
pathname.
•
The MAXDIRTYINODETIME option is meaningful only for filesets that use the
BUFFERED LOG option.
A fileset with an updated (flushed) inode cache is considered “clean” instead of
“dirty” and does not need recovery after a failure. The more often the inode cache
is flushed, the less likely a fileset is to be corrupted by a failure and to need
recovery after the failure.
The larger the value specified for seconds2, the more likely that a fileset recovery
is needed after a failure, but the faster fileset access becomes because fewer disk
writes occur to update the cache from memory. The smaller the value for
seconds2, the less likely that a fileset recovery is needed after a failure, but the
slower fileset access becomes because more disk writes occur to update the
cache from memory.
Fileset recovery delays subsequent availability of the fileset, so the tradeoff for
slightly faster current access is increased probability of delayed access after a
failure.
•
The MAXINODES value specifies an upper bound on the number of inodes that
can be created in the fileset. It does not guarantee that MAXINODES number of
inodes will be created in the fileset. Specifying a large MAXINODES value
increases the fileset recovery time in the case of an outage. HP recommends that
you specify a MAXINODES value less than or equal to 1000000.
Examples
•
To add the fileset USER1 with the storage-pool file ZOSSPOOL using the volume
catalog on $DATA1 and the mount point /user1, enter the following command:
ADD /OUT CMDLOG/ FILESET $ZPMON.USER1, CATALOG $DATA1, &
POOL ZOSSPOOL, MNTPOINT "/user1", &
BUFFERED LOG, NAMESERVER #ZPNS
This command:
°
Sends informational messages to the file CMDLOG.
°
Specifies the fileset name as USER1 and the mount point as /user1.
°
Specifies that files created in the fileset USER1 are stored on the disk volumes
listed in the storage-pool file ZOSSPOOL.
°
Specifies that the catalog files for the fileset /user1 are stored on the disk
volume $DATA1.
°
Assigns the fileset USER1 to the OSS name server process $ZPNS, which has
the server name #ZPNS.
°
Buffers only output to the PXLOG file.
