Set up disk for veritas
/usr/lib/vxvm/bin/vxdisksetup -i emc0_01ec
Add disk to existing diskgroup and maintain existing disk names
vxdg -g QZUCRINSI312_sybdg01 adddisk disk_01ec=emc0_01ec
Check by how much the volume would grow
vxassist -g diskGroup maxgrow vol_sybdg01 alloc="disk_01ec disk_01ed disk_01ee disk_01ef disk_01f0 disk_01fa disk_01fb disk_01fc"
will print something like : 15019741184
Grow the volume
/usr/lib/vxvm/bin/vxresize -g diskGroup vol_sybdg01 15019741184 disk_01ec disk_01ed disk_01ee disk_01ef disk_01f0 disk_01fa disk_01fb disk_01fc

we see we have a stripe , if you just try to all a block of storage to it veritas will error
vxassist maxsize shows a value , but maxgrow does not :(
the reason is you must maintain the coloum count on the stripe! in this case 4
(the storqe we have is also bigger than the 64GB lun size used before)
the solution is to create many subdisks :
vxdg -g ORAVOL1_dg adddisk disk701=c2t50060E801531B302d508s2
vxmake -g ORAVOL1_dg sd disk701-01 disk701 len=134219008 offset=0
vxmake -g ORAVOL1_dg sd disk701-02 disk701 len=134219008 offset=134219008
vxmake -g ORAVOL1_dg sd disk701-03 disk701 len=134219008 offset=268438016
vxmake -g ORAVOL1_dg sd disk701-03 disk701 len=134219008 offset=402657024
... USW
vxsd -g ORAVOL1_dg -l 0 assoc oradata02-01 disk701-01
vxsd -g ORAVOL1_dg -l 1 assoc oradata02-01 disk701-02
vxsd -g ORAVOL1_dg -l 2 assoc oradata02-01 disk701-03
vxsd -g ORAVOL1_dg -l 3 assoc oradata02-01 disk701-04
... USW
use vxassist maxgrow now to workout the value to put in the the resize
/usr/lib/vxvm/bin/vxresize -g ORAVOL1_dg oradata06 1610240000
now we have :
v oradata02 - ENABLED ACTIVE 1610240000 SELECT oradata02-01 fsgen
pl oradata02-01 oradata02 ENABLED ACTIVE 1610240000 STRIPE 4/128 RW
