On my ancient Pegasus2 R6 system, one of the disks has developed a red light. 

I have completely forgot everything about system maintenance on this program.

I have just reinstalled the Promise Utility program (4.06.0000.04 (C04).  But that seems to just run a program called Instruments.  I vaguelly recollect a function to check the disk status on ths program.

How do I fix the red light issue?

If I go to terminal and type promiseutil I get the program.  Type help and I get the list of commands

Only 3 disks are in the array.  LD 0.  has a MAJOR error 0x00090004. Dec 27.  Logical drive has been set to critical.  Drives 1, 2, & 3.  Drieve 2 has a red X.  Looks like 323 Minor 'bad sector' found on Disk warnings.

Used promiseutil phydrv -a online -p 2 to force drive back online

Used promiseutil array -a accept -d 0 to force array back online

Looks like it is working again.  Now what...

Started a Redundancy check.  Then Media Patrol. Then Spare check.
