Adding LUNS / Extending LUNS

How do you add a LUN on a VA 7410? How do you extend a LUN if required?

Thanks,

Hi Halili,

1. Load Exceed / any other Xterminal software on your windows PC.

2. Set the display in the unix server shell where the VA is connected as follows.

#export DISPLAY=:0.0

3. In unix shell run
#launcher &

4.expand local host and select the storage name. Right click and run HP storage works command view SDM.

5.In CV SDM go to Lun Management.

6.Click on create lun. Then one of the redundancy group and type the capacity in GBs. Also Note down and document the Lun number.

7. After this do the following in unix shell.

#ioscan -f
#insf -e
#ioscan -fnC disk

Now you will find a new disk device in the ioscan list.

8. Now do the normal procedure to make the file system with this device. Hope you are comfortable with LVM commands.

Pls reply with your observations.

regards,
Syam

halili,

There is no option for extending the lun with CV SDM. More over its not useful to extend the lun, if you are not having veritas volume manager installed in your machine.

If you want to increase your filesystem size , then go on creating new luns and add it to the respective logical volumes and then do #extendfs. Else #fsadm if you have online jfs with you.

Both Veritas volume manager and online jfs require seperate licence.

Adding LUNs: you uses one of three ways(command line, cvui, launcher)(required installed Command view SDM)
1. Command Line:
Create Lun 30M Redundancy group 2
armcfg -a 30 -g 2 myArrayID
2,Cvui
just type cvui at prompt
