Creating & extending a file system with HP-UX LVM

Step 1: Scan the disk & make it visible on the server

#insf -e (create device files for any newly added devices)
#ioscan -fnC disk

Step 2: Create a physical volume

#diskinfo /dev/rdisk/disk210 (check disk size)
#pvcreate /dev/disk/disk210

Step 3: Create the volume group

#mkdir /dev/vgignite
#ll /dev/*/group (check for currently create group special device files)
#mknod /dev/vgignite/group c 128 0x010000 (create new group device special file specifying the major & minor numbers as 128 &0x010000 )

The major number signifies the type of device file & minor number will uniquely identify the device.

#vgcreate -V 2.0 -s 64 -S 4t /dev/vgignite /dev/disk/disk210

Step 4: Create a logical volume

#lvcreate -L 256000 -n lv_ignite -s y /dev/vgignite (size is in MB)
#lvdisplay /dev/vgignite/lv_ignite

Step 5: Create & mount the file system

#newfs -F vxfs -o largefiles /dev/vgignite/rlv_ignite
#mount /dev/vgignite/lv_ignite /ignite_depot


To extend the file system:

Step 1: Extend the logical volume:

#lvextned -L 512000 -n lv_ignite /dev/vgignite (size is in MB)

Step 2: Extend the file system:

#fsadm -F vxfs -b 512000M  /ignite_depot
