How to Create LUN on VA7100?

Hi Experts,

Customer Have a L2000 connect to VA7100. Currently they want add 7x73GB into the existing VA7100. I have few questions would like to ask,

1. Does the Command View SDM come with VA7100 ?
if dont have Command view and can we use command line to create new lun ?
2. Can the experts tell me how to use command line to create the new LUN.
3. Another scenario, if the 7 Hdds add to exist Lun, how to config via command line?
4. If the existing VA7100 was RAID protect,what should I do after create the LUN?

Best regards
Leon

Hi,

Normally you have commandview delivered with your VA. If you don't have commandview you can use the serial connection to create a LUN (vfpcfg with an optioan)

The most easy command line to create a lun is with the command cvui, which is a port of commandview

You can't extend a LUN, you have to create an other and extend your volumegroup under unix.
All the luns have the same raid level in a VA7100

Hi,
If auto include is enabled (default)in the Array, then the new disks will be automatically included in the array.

CV-SDM comes free with VA7100.

You can create LUN using CV-SDM.

in hp-ux run /opt/sanmgr/commandview/client/cvui
if CV-SDM is already installed on the host.

You can also connect a serial terminal to Array controller and create LUN. (not recommended, since there is no much details like used space/ free space)

RAID level cannot altered in VA7100.
If the first redendancy group (RG) created in AutoRAID (default), then all LUNs can only AutoRAID.

Va7100 suports only AutoRAID, RAID1+0

Re: How to Create LUN on VA7100?

example from command line

cfg -L 1 -a -g 0


-L is to add logical volume, the number is the vol id.

-a is to add capacity

-g is for redundancy group id

you should be able to see your lun from an ioscan.

--To go forward, you must backup

1. Yes. If you do not have commnand view you still can create LUN by connect serial cable to console port of VA7100 and issue
#man cfg
2. commmand view VA commad
For example: To create a LUN numbered 17 with a capacity of 30MB associated
with Redundancy group2 on array with alias of myarray
armcfg -L 17 -a 30 -g 2 myArray
3. can not add more disk to LUN, you can only add disk to Redundancy group
4, You can specify which RAID you use when creating LUN
