Hi:

While I prefer using the LVM commands, I would suggest that you use SAM until you understand the paths involved.

A summary of LVM commands and their use can be found in the 'lvm(7)' manpages.

http://docs.hp.com/en/B2355-60127/lvm.7.html

A much more detailed discussion about setting up LVM and filesystems is covered here:

http://docs.hp.com/en/B2355-90950/index.html

Even if you elect to use SAM, I urge you to read the aforementioned documents.

Regards!

you must first create a logical volume

lvcreate -L (size) -n (logical volume name) vg??(volume group name)

newfs -F vxfs -o largefile /dev/vg??/lvol??

mkdir ???

mount -F vxfs /dev/vg??/lvol?? /(new mount point)

add entry /etc/fstab

or just use sam

Shalom,

lvcreate -n logicalvolumename vg##
lvextend -L size in M /dev/vg##/logicalvolumename
newfs -F vxfs /dev/vg##/rlogicalvolumename
# extend existing extendfs /dev/v##/rlogicalvolumename

I believe you used my mail form to contact me on a SG issue. The email address you used was not valid and I was unable to reply. If I am correct, please try again.

It's very simple:

1) Create a new LVOL using lvcreate (or dedicate an entire disk to a filesystem).
e.g. lvcreate -L 512 -n lvol4 /dev/vg02

2) newfs -F vxfs /dev/vg02/rlvol4

3) Create a mountpoint
e.g. mkdir /mickey

4) Create an /etc/fstab entry:
/dev/vg02/lvol4 /mickey vxfs rw,suid,delaylog 0 2

5) mount /mickey

OR use SAM -> Disks and Filesystems to do all of these tasks.

sam is not good way to create filesystems.

Command line is best option to create.

1. Initialize disk using pvcreate command
2. mkdir /dev/vgname
3. mknod /dev/vgname/group c 64 0x??0000
where ?? - minor number and shouldn't be used. you can check using ll /dev/vg*/group
4. vgcreate /dev/vgname physical volume1 ..
5. lvcreate -L new size /dev/vgname
6. newfs -F vxfs -o largefiles /dev/vgname/rlvol??
7. mkdir /mountpoint
8. add entry into /etc/fstab
/dev/vgname/lvol?? /mountpoint vxfs delaylog 0 2
