Re-Create an array pool connected to VPLEX

Question

Hi all, an customer has expandet the wrong VNX-Pool with additional Disks. Now the customer has the need to free up these disks and give it to the right pool. BUT: To do this, i´ve to delete the pool and re-create it. My question points to the LUNs in this pool, because 30 of these LUN a are provisioned to VPLEX for distributed devices. Is there any documentation that descripes the procedure i´ve to do on Vplex? I´ve found a video 'How to remove faulty leg from a distributed device'. I´m not sure, wheter i can use this as a way... Hope, someone can help me. Thanks in advance Karl

Hi Karl,

you would identify another pool where new luns can be created and perform a lun migration on the VNX. At the end of the VNX lun migration, the old lun gets deleted and the new lun will have the same Lun ID, naa / wwn , data and host access. So, there is no change in the properties of the Lun.

Since there is no change to the lun properties, VPlex will not find any changes and you don't have to perform anything in VPlex.

Hope this helps.

Thanks,

Hi Sathyaprakash, thanks for your reply and sorry for the delay.

it sounds easier as it is. There is no space and no free disks were i can migrate to. So I need e way to split the distributed device, detach all luns from vplex and rebuild the pool with the correct amoun of disk. After that Sync the existing virtual volumes on the remaining side with the new created. But I cannot find any documention that helps me with the doings on vplex.

Thanks
