Experts,
I need to change the batteries of our UPS so I need to switch everything off before I start. And I don't know where to start.
we have 2 hyper-v , HV1 and HV2. (HP DL360)
we have 6 virtual servers.
we have SAN (MSA1040)
Microserver (HP G2020)
Could you please help me. what do i switch off first and how? and in what order?
then once i am done with the UPS, how to switch all back on and the order?
Thank you for your help
1. Shutdown virtual machines (first applications, databases - if any) either via console, RDP, SSH.
2. Shutdown Microserver if it is being used as an application server or database server.
3. Shutdown Hyper-v servers (any order)
4. Shutdown SAN
Power on sequence is opposite to above sequence.
1. Power on SAN
2. Power on Hyper-v servers
3. Power on database servers (VMs on physicals)
4. Power on all other application servers (VMs on physicals)
