Storage Checkpoint Administration
Storage Checkpoint administrative operations require the fsckptadm utility (see fsckptadm (1M)). You can
use the fsckptadm utility to create and remove Storage Checkpoints, change attributes, and ascertain
statistical data. Every Storage Checkpoint has an associated name which allows you to manage Storage
Checkpoints; this name is limited to 127 characters and cannot contain a colon (:).
Creating a Storage Checkpoint
You can create a Storage Checkpoint using the fsckptadm utility. In these examples, /mnt0 is a mounted
VxFS file system with a Version 4 disk layout.
This example shows the creation of a nodata Storage Checkpoint (see “Space Management Considerations” on
page 64) named thu_7pm on /mnt0 and lists all Storage Checkpoints of the /mnt0 file system:
# fsckptadm -n create thu_7pm /mnt0
# fsckptadm list /mnt0
/mnt0
thu_7pm:
ctime= Thu Jun 1 19:02:17 2001
mtime= Thu Jun 1 19:02:17 2001
flags= nodata
This example shows the creation of a removable Storage Checkpoint named thu_8pm on /mnt0 and list all
Storage Checkpoints of the /mnt0 file system:
# fsckptadm -r create thu_8pm /mnt0
# fsckptadm list /mnt0
/mnt0
thu_8pm:
ctime= Thu Jun 1 20:01:19 2001
mtime= Thu Jun 1 20:01:19 2001
flags= removable
thu_7pm:
ctime= Thu Jun 1 19:02:17 2001
mtime= Thu Jun 1 19:02:17 2001
flags= nodata
