Hi,
I am relatively new to NetApp, although very experienced on other arrays.
I need to upgrade a 6290 from 8.1.2 7 mode to 8.2.2 P2 7 mode.
Upgrade advisor reported that I have 334 disks of Model x480_HMKPE04TSDB that have outdated firmware.
Upgrade advisor also recommended that I manually download the disk firmware and update it manually. It was stated this was a prerequisite for ndu upgrades.
Then I read in another document that each disk would be offline for 2.5 minutes when the disk firmware updated. For 334 drives, it would take 835 minutes or 14 hours.
I can't have my users offline on this array for 14 hours.
I must not understand this correctly.
Can someone please help me understand how to upgrade the disk firmware on 334 drives without user downtime of 14 hours?
Thanks,
