A few weeks ago, I was busy on the servers and SAN storage migration to a new DataCenter.

Here is the order for Powering down process for the SAN Storage:

Power down steps:

  1. Hosts
  2. Storage Arrays
  3. SAN Switches


And it is brought up in the reverse order. When powering up your Storage array, please power up all the enclosures first and make sure all the disks are online before powering up each SPS.


Power up steps:

  1. SAN Switches
  2. Storage Arrays
  3. Hosts
