I have two hosts directly connected to a VNX 5200 within a Storage Group. These hosts no longer have any virtual machines and need to be retired and removed.
As far as best practices go, I cant seem to find any documentation regarding this with EMC.
My process so far would involve:
1. Remove the old hosts from the storage group within navisphere, by editing the storage group and moving old hosts from right to left
2. Remove the physical cabling between the HBA and the VNX FC ports
3. Deregister the intiator via unisphere
I am assuming this has no downtime/interruption effect on the existing LUN’s and other online hosts? Am I correct in assuming this?
Would this be a recommended procedure?
