Hi,
If you already have vg then just using lvcreate command you can create new lv see the example
lvcreate -L sizeinMB -n myvolume vgname
here -L Size of logical volume in megabytes
-n is name of your lv.

#lvcreate -L 1024 -n lvol4 vg03
#newfs -F vxfs -o largefiles /dev/vg03/rlvol4
#mkdir /data
#mount /dev/vg03/lvol4 /data
add entry into /etc/fstab
# vi /etc/fstab
/dev/vg03/lvol4 /data vxfs defaults 0 2

same you can do using shm in 11.31

Hi,
A good white paper about 11.31 and lvm v2
http://docs.hp.com/en/lvm-v2/L2_whitepaper_8.pdf
In this case you use for example the option -V.
Hope it helps

Hi ,

thanks for all replys ..

i ahve assineged few luns from storage and should i use insf or something else to create persistent device (/dev/dsk/diskNN)

[Mark S Meadows]

The persistent device files reside under /dev/disk/* and /dev/rdisk/* respectively.

The commands you need to run are :

ioscan -funNCdisk
insf -eCdisk
ioscan -funNCdisk

Dear All,

if i do insf ,whether it will create both /dev/rdsk/cxtxdx and /dev/rdisk/diskNN ????

[Mark S Meadows]

If you run the above command insf -eCdisk it should create both the legacy and persistent device files, i.e. :

/dev/dsk/*
/dev/rdsk/*
/dev/disk/*
/dev/rdisk/*

if the new luns have been presented to the system and the system can see them.

Mark
