Can someone let me know how to upgrade disk firmware and DQP. Does it needs downtime or can be done in the background.
Refer KB https://kb.netapp.com/index?page=content&id=1010762 for the procedure to updaate firmware.
Disk firmware upgrade does not need downtime & can run in the background. refer https://library.netapp.com/ecmdocs/ECMP1511538/html/man1/na_disk_fw_update.1.html#toc
Wil it be causing any disruption ?? I am doing it on a HA pair for SATA 2TB disks
Disk firmware update is non disruptive. Refer https://kb.netapp.com/support/index?page=content&id=3011892
The KB says for CIFS it is applicable to SAN environment as well ?
