Just need some guidance please.
One of the three psu's developed a fault on a compaq proliant 8000. i have a replacement and just wondered if i should just whip out the old and insert the new without turning off the power. My anxiety (and may be totally unfounded due to lack of experience/knowledge) is that a possible power disturbance might damage the hard drives. One drive has already gone down and i think this may have been caused by the power failure so i am down to three disks on a Raid 5 set up. I realise that if i lose one more then i may lose all the data (currently frantically backing up the whole server at the moment).
Thanks in advance.
