SAN snapshots (possible FC/multipath issues)
Hi all,
Since my previous question, I reinforce my wish to a great and fantastic week for everyone.
Since some years using SAN snapshots when performing intrusive changes on VMs, such as OS updates/upgrades, and for sometimes those snapshots were in deed very useful, I recently moved to a new SAN (Dell Unity 480 certified by Oracle for OVM 3.4 since 2016) and did the same as usual which consists in creating a SAN snapshot of all the LUN's of a VM, then I do the changes on the VM and when needed I reboot the VM. So far so good.
When I need to "rollback" the changes, I stop the VM, then once again on the SAN software management, I restore de snapshot and star the VM again. So far so good (once again...)
