Great. &nbsp;Thanks for the help Andy.

 I'm trying to see how much trouble it would be to replace an MSA30.<br />

I believe one of my MSA30s has a bad backplane. &nbsp;I'm thinking the backplane is bad because slot #5 always shows a bad drive. (I've tried 3 good drives)<br />

I'd like to have someone let me know if they think I'm right or wrong. &nbsp;Also, could there be another explanation for 1 drive bad always showing as bad? &nbsp;On one post, someone had written about updating the firmware on an MSA30 but I didn't think it had any components that had firmware and I couldn't find any MSA30 firmware from the HP site.<br />
<br />
The MSA30 is connected via scsi to an MSA1500 and fibre channel from there. &nbsp;the drives are scsi. &nbsp;I'm attaching a copy of the diagnostics from ACU.<br />

expected issues with swapping out an MSA30

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
