When trying to remove it, we got a warning that the array may be unavailable if we proceed. So, we checked previous answers from this forum regarding similar situations. We found out that LUN 0 is used by the VA management software and its size should be 10 MB.
Is that correct? How can we reduce this LUN from 360 GB to 10 MB?
I'd appreciate your help. Thanks
Solved! Go to Solution.

Re: Remove LUN 0 on VA7400
Remove all the data from the LUN. Make sure its backed up of course. Then use the lvreduce command to reduce the logical volume from 360 GB to 10 MB.

Re: Remove LUN 0 on VA7400
All you have to do is remove the VG and free up the LUN. Make sure that LUN is not active on the system by running the command "pvdisplay /dev/dsk/cxt0d0".
Then using VA management software, reduce it to 10 MB. Run 'ioscan -f' on the system and ensure that the size is reduced.

Re: Remove LUN 0 on VA7400
there is no way if reducing it. The only thing You can do is to delete it and make a new LUN0 with size of 10MB. I suggest having the serial cable for the VA ready and connected, in case Your CV software loses mgmt access after lun0 deletion. Then You can always use terminal access through serial port and put a command
cfg -L 0 -c 10M (hope the syntax is correct, haven't workd with the VA for quite a time...).
By deleting LUN0, You can lose MGMT access to the array (for VC software), and if You do not run ioscan while the LUN0 is deleted, other LUNs should be fine.

Re: Remove LUN 0 on VA7400
LUN is at physical level and LV is at logical level. LV's are created on LUN.
LUN's are not flexible as LV's and hence they can't be reduced or increased.
You have to delete it and recreate.
Hope that helps.

Re: Remove LUN 0 on VA7400
Armcfg is for create and delete Luns.
You need delete the Lun armcfg -L (lun) -d array-id and then recreate the Lun.
armcfg -L (lun) -a 10 -g (groupId) arrayID

SolutionThe 10MB LUN 0 remendation is for shared environments that might include Windows. LUN 0 must be present for Windows to discover the array.
