mfiutil reports "PSTATE 0x0020" new drive state

[Charles Owens]

  Hello,

We have a mfi-based RAID array with a failed drive.  When replacing the 
failed drive with a brand new one 'mfiutil' reports it having status of 
"PSTATE 0x0020".  Attempts to work with the drive to make it a hot spare 
are unsuccessful (eg. using "good" and/or "add" subcommands of 
mfiutil).   We've tested procedures for replacing failed drives in the 
past and haven't run into this.

Looking at the code for mfiutil it appears that this is happening 
because the mfi controller is reporting a drive status code that mfiutil 
doesn't know about.  The system is remote and in production, so booting 
into the LSI in-BIOS RAID-management-tool is not an attractive option.

Any help with understanding the situation and potential next steps would 
be greatly appreciated.  More background information follows below.

Thanks,

Charles
