How to Create LUN on VA7100?
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

Re: How to Create LUN on VA7100?
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

Re: How to Create LUN on VA7100?
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?
cfg -L 1 -a
-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.

Re: How to Create LUN on VA7100?
#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
