Hot-Add MD1200 to MD3220i
Posted on 2013-01-17
I have a Dell MD3220i which I intend to expand with an MD1220 DAS unit. Does anyone have any experience of hot-adding these units to an MD3220i?
The corporate bumf on the MD3220i states you can hot-add external enclosures without powering down the system.
Some people recommend powering down the MD3220i, connect and power up the MD1220, and then power up the MD3220i again (which makes sense)
A Dell tech said I could hot-add the MD1220 without affecting the existing configuration (i.e without any ill-effect) however, it might not behave correctly until I reboot each RAID controller.
Essentially, I am terrified of screwing up the MD3220i as it holds the vast majority of the company VMs, and won't be able to get downtime for weeks (but need the extra capacity pronto)
