Before we actually start using DMP admins 1st need to check to whether the Veritas ASL (Array support Library) for the specific array is installed .
#vxddladm listsupport
The above command will list you all the libraries that are installed and the storage that is being supported. If the specific storage library is not present then get the same from Veritas. Once installed you can check the same with below command
#vxddladm listsupport libname=
It will show you the exact storage model and the controller version that is being supported.
Once the above is done then admin can go ahead with using the disk.
Command to configure the new disk and see the same
#devfsadm
#format
Format the above disk and run
#vxdctl enable
#vxdisk list
Now the new disk is under Veritas and can be used now.
Other primarily use DMP commands
#vxdisk list
#vxdisk path
#vxdmpadm iostat show all
The below commands are used for initializing, creating disk group, volumes and snapshots etc.
#vxdisksetup -i c1t0d0s0
#vxdg init datadg datadg01=c1t0d0s0
#vxdg -g datadg add disk datadg02=c2t0d0s0
#vxassist -g datadg make datavol 10m layout=mirror (can use stripe also)
#mkfs -F vxfs /dev/vx/rdsk/datadg/datavol
#mount -F vxfs /dev/vx/dsk/datadg/datavol /FS
To create a mirror volume
#vxassist -g datadg mirror datavol
To create mirror to a specific disk
#vxassist -g datadg mirror datavol datadg03
To remove a plex that contain subdisk from from disk datadg02
#vxassist -g datadg remove mirror datavol !datadg02
Resizing commands
#vxresize -g datadg datavol 50m
#vxresize -g datadg datavol +50m
Removing a disk
#vxassist -g datadg remove volume datavol
#vxdg -g datadg rmdisk datadg02
#vxdg destroy datadg (for the last disk)
Snapshots
#vxassist -g datadg -b snapstart datavol
#vxassist -g datadg snapshot datavol snapvol
Reassociate
#vxassist -g datadg snapback snapvol
Deassociate
#vxassist -g datadg snapclear snapvol
Destroy
#vxassist -g datadg remove volume snapvol
Checking the size of DG
vxprint -g vg01 -dF "%publen" qwk `BEGIN {s = 0} {s += $1} END {print s/2097152, "GB"}`
