vxmake plex plex layout=stripe|raid5 stwidth=W ncolumn=N sd=subdisk1[,subdisk2,...] 创建条带式 plex 或 RAID-5 plex。
vxmake -Uusage_type vol volume [len=length] plex=plex,... 从现有 plex 创建卷。
vxmend on plex 重新启用 plex 以供使用。
vxplex att volume plex 将 plex 挂接到现有卷。
vxplex det plex 分离 plex。
vxplex off plex 使 plex 脱机以便进行维护。
vxplex mv oldplex newplex 替换 plex。

Snapshot:
Creating and Managing
Traditional Volume Snapshots
Create
vxassist -g diskgroup [-b] snapstart origvol
# vxassist -g datadg -b snapstart datavol
vxassist -g diskgroup snapshot origvol snapvol
# vxassist -g datadg snapshot datavol snapvol
Reassociate:
# vxassist -g datadg snapback snapvol
or
# vxassist -g snapvol datadg -o resyncfromreplica snapback
Dissociate:
# vxassist -g datadg snapclear snapvol
Destroy:
# vxassist -g datadg remove volume snapvol
Creating and Managing Full-Sized
Instant Volume Snapshots
Create the snapshot volume using one of these methods:
Specify an empty volume to be used as the snapshot:
vxsnap -g diskgroup make source=origvol/snapvol=snapvol
Break off an existing plex to create the new snapshot:
vxsnap -g diskgroup make
source=origvol/newvol=snapvol/plex=name
Update:
vxsnap –g diskgroup refresh snapvol source=origvol
vxsnap –g diskgroup reattach snapvol source=origvol
vxsnap –g diskgroup restore origvol source=snapvol
vxsnap –g diskgroup dis snapvol
Remove:
vxedit -g diskgroup -r rm snapvol
----
Creating and Managing Space-
Optimized Instant Snapshots:
Create a snapshot and cache object at the same time:
vxsnap -g diskgroup make
source=origvol/newvol=snapvol/cachesize=size
Example:
# vxsnap -g datadg make
source=datavol/newvol=snapvol/cachesize=1g
Update:
vxsnap –g diskgroup refresh snapvol source=origvol
or
vxsnap –g diskgroup restore origvol source=snapvol
Remove the snapshot, then stop and remove the cache object:
vxedit -g diskgroup -r rm snapvol
vxcache -g diskgroup stop cache_object
vxedit -g diskgroup -r rm cache_object
File System Snapshots:
Create
mount -F vxfs -o snapof=origfs[,snapsize=size]
destination snap_mount_point
# mount -F vxfs
-o snapof=/dev/dsk/c0t6d0s2,snapsize=32768
/dev/dsk/c0t5d0s2 /snapmount
Refresh:
# mount -F vxfs -o
remount,snapof=/dev/dsk/c0t6d0s2,snapsize=32768
/dev/dsk/c0t5d0s2 /snapmount
Remove:
umount snap_mount_point
# umount /snapmount
Storage Checkpoints:
Create:
fsckptadm [-nruv] create ckpt_name mount_point
# fsckptadm -v create thu_7pm /checkpt1
Mount:
mount -F vxfs -o ckpt=ckpt_name
/dev/vx/dsk/diskgroup/vol:ckpt_name /mount_point
# mount -F vxfs -o ckpt=thu_7pm
/dev/vx/dsk/datadg/vol1:thu_7pm /checkpt1
Unmount:
By mount point:
# umount /fsvol_may_23
By pseudo device name:
# umount /dev/vx/dsk/datadg/vol1:may_23
Convert:
fsckptadm [-sv] set {nodata|nomount|remove}
ckpt_name mount_point
# fsckptadm set nodata thu_7pm /checkpt1
Set quotas:
fsckptadm [-fm] setquotalimit mount_point
hard_limit soft_limit
# fsckptadm setquotalimit /checkpt1 1024 512
Remove:
fsckptadm [-sv] remove ckpt_name mount_point
# fsckptadm remove thu_7pm /checkpt1
