The storage team needs to upgrade the firmware on the test environment clustered storage array while minimizing downtime. Which of the following BEST describe what the storage team should consider…

The correct answer is B. RAID controllers C. Disk firmware. Before upgrading firmware on a clustered storage array, the team must verify that RAID controller firmware and disk firmware are compatible with the new array firmware to avoid failures and downtime.

Why each option

Before upgrading firmware on a clustered storage array, the team must verify that RAID controller firmware and disk firmware are compatible with the new array firmware to avoid failures and downtime.

AFiber cable types

Fiber cable types are passive physical components that are unaffected by a firmware upgrade and present no compatibility risk during the process.

BRAID controllersCorrect

RAID controller firmware must be validated against the target array firmware version because incompatible controller firmware can cause drives to go offline or the cluster to lose quorum during or after the upgrade. Disk firmware (C) is equally critical because storage vendors publish tested compatibility matrices pairing specific array firmware versions with specific disk firmware revisions, and deviating from the matrix risks data unavailability or drive errors post-upgrade.

CDisk firmwareCorrect

Disk firmware (C) is equally critical because storage vendors publish tested compatibility matrices pairing specific array firmware versions with specific disk firmware revisions, and deviating from the matrix risks data unavailability or drive errors post-upgrade.

DVirtual machine OS

The virtual machine operating system operates at a layer above the storage subsystem and does not influence or constrain storage array firmware compatibility.

EIPMI software version

IPMI software version governs out-of-band server management and is independent of storage array firmware compatibility requirements.
