Why it is dangerous to turn off storage arrays even in extreme cases?

  • 772

I have read in a couple of places that when you are in the situation in which there are no spare disks and the RAID level doesn't protect you from another disk failure, some administrators choose to turn off storage until the new storage drives arrives.

However, I came across various vendors that advice against turning off storage unless you are replacing a a controller in a single controller system.

So, when the data is at serious risk if one more drive fails, why would be a bad idea to turn off the storage?

Thanks in advance!

    Start up / shutdown is harder on the disks than continuous operation.

  2. Because your data is at risk with a sudden power loss as well. If you do a CLEAN/ordered shut down, I don't see what the issue would be.
