VxVM Basic Tasks

So here I am with a little more knowledge about this wonderful Volume Manager.

This information is dedicated for HP ITRC Forum who helped me their best. And this information is true for VXVM implementations on HPUX.

Defining a disk for use of VXVM

a). /etc/vx/bin/vxdisksetup -i /dev/cXtXdX

Creating a Disk Group

a). vxdg init disk01=cXtXdX

Extend an existing Disk Group

a). vxdg -g adddisk disk02=cXtXdX

Create a Volume on a disk group

a). vxassist -g make 10g

Create a Volume on a disk group on a specific disk

a). vxassist -g 1g alloc=disk20

Create a Striped Volume

a). vxassist -g make stripevol 20g layout=striped ncols=4 stwidth=128

Create a Filesystem on a vol

a). mkfs -F vxfs-o bsize=8192,largefiles /dev/vx/rdsk//oravol01

Update the /etc/filesystems

a) vi /etc/fstab

Display a volume Group

a). vxprint -g disk_group

Display a Volume

a). vxprint -ht vol_name

Increase a filesystem

a). vxresize -b -F vxfs -t homevolresize homevol 10g disk10 disk11

Mirroring a rootdg

a). vxdisksetup -iB cxtydz (To initialise disk under Volume manager)

b). vxdg -g rootdg adddisk rootdisk=cxtydz ( To add the disk to the Disk Group)
c). vxrootmir -v -b -R cxtydz ( To create the mirror)
