Creating filesystems on SAN

[jmckinzie]

I have several partitions that I need to create on the SAN.

I know I have to do a pvcreate, vgcreate for these SAN disks but don't know exactly the process. Any ideas?

I have 11 partitions that I need to make at different mount oints. I have included to here....


/aqua/v1/CREDIT_SCORE 16.0gb
/aqua/tpwk 18.0GB

-TIA

Can you provide the LUNs that have been made available to you thru

# ioscan -funC disk

~thanks

The best way for you is to go with SAM.

run SAM -> disk devices

and create a new volume group with the presented devices, create LVOLs of needed size and mount points. SAM will guide you.

Are you the admin of this server?

are you creating a new volume group with the new disks????

if so, after validating you can see the new disks: ioscan -funC disk or you can run insf -e to create the special file then an ioscan -f to pick up the paths...

after that it will be like so
pvcreate /dev/rdsk/c?t?d?

mkdir /dev/vg????
mknod /dev/vg????/group c 64 0x0?????
vgcreate /dev/vg??? /dev/dsk/c?t?d? /dev/dsk/c?t?d? (alternate link)

vgextend /dev/vg?? /dev/dsk/c?t?d? /dev/dsk/c?t?d?

lvcreate -L 18000 /dev/vg??
lvcreate -L 16000 /dev/vg??

mkdir /aqua/v1/CREDIT_SCORE
mkdir /aqua/tpwk

newfs -F vxfs -o largefiles /dev/vg??/lvol1
newfs -F vxfs -o largefiles /dev/vg??/lvol2

mount -F vxfs /dev/vg??/lvol1 /aqua/v1/CREDIT_SCORE

mount -F vxfs /dev/vg??/lvol2 /aqua/tpwk

add the entries to your /etc/fstaba and you should be set.

Hi,

The simplest way in your case is to use SAM. Ensure that LUNs are visible, start SAM and go to disks. You will have to create volume group, to build logical volume and to create file system (there is an option for that).

If you want to do all this manually, so:
For each /dev/dsk/cXtYdZ do:
pvcreate /dev/rdsk/cXtYdZ
mkdir /dev/vgNN
mknod /dev/vgNN/group c 64 0x0L0000
(0L is a unique hex number for each VG)
vgcreate /dev/vgNN /dev/dsk/cXtYdZ
vgchange -a y vgNN
vgdisplay vgNN

Look for "Free PE PPPP"
lvcreate -l PPPP vgNN
newfs -F vxfs /dev/vgNN/rlvol1
mkdir /FS_NAME1
mount /dev/vgNN/lvol1 /FS_NAME1

etc....

HTH

Thanks Victor.
