One of the first step is to type:

# cfgadm -al

To see if the OS can see the disk, if it is, then use "format" command to lable them one by one, and partition each disk, etc.

Thanks ganjos. Do you have any documentation on how to label and partition the disks? Also, expand VxFS in a 3 node tier? I have been thrown into this role. Any help is appreciated!

If they're going to be used  with VxVM, labelling them should suffice. To save time when formatting(lalbing) many disks set the following env variable:

NOINUSE_CHECK=blah

Setting the above will prevent format going off and checking whether the disk is currently in use. Formatting a long list of devices becomes much quicker, e.g. :





echo label > /var/tmp/fmtcmd
for i in `vxdisk list | nawk '/nolabel/ {print $1}'`;do 
dev=`vxdmpadm getsubpaths dmpnodename=$i |tail -1 |awk '{print $1}'`;
format -f /var/tmp/fmtcmd $dev;
done

Hi Rowley. Yes, VxVM is involved. A 3 tiered node. I have to expand the VxFS first on one node. It keeps going up to 98%. Which is why we got the new disks.

great resource: http://www.cuddletech.com/veritas/

cfgadm -al
devfsadm -Cv

label your disks

vxdisk scandisks
vxdisksetup your disks
add disks to your disk group

See how much you can extend by, if just one volume:
vxassist -g mydg maxgrow v_myvol01

resize:
vxresize -g mydg v_myvol01 +[sector value from previous command]

To grow using specific disks:
vxassist -g mydg maxsize alloc=disk10,disk11,disk12
 
then resize:
vxresize -bxg mydg v_myvol01 +[sector value from previous command] alloc=disk10,disk11,disk12
