Subject:  Fixing Mirrored Drive Nds_Maint Problems.
 Source:  TAC


There are occasions when one partition of a mirrored disk pair will
report
the status of Nds_Maint.  Using the metadetach and metattach commands
will
usually correct this problem.

Note: The following procedure was done on a AP50.  The same procedure
will
work on a 51 series but the Metamirror and Submirror device  names will
be
different.

Run the dft show_status command to view the mirrored status of the
system's
hard drives:

21AP50# dft show_status

Metamirror      Submirror      Size       Device        State

 /dev/md0a:     /dev/md4a:     20160    ESP0 / SCSI3    Okay
                /dev/md8a:     20160    ESP1 / SCSI3    Okay
 /dev/md0b:     /dev/md4b:     47520    ESP0 / SCSI3    Okay
                /dev/md8b:     47520    ESP1 / SCSI3    Okay
 /dev/md0e:     /dev/md4e:     39600    ESP0 / SCSI3    Okay
                /dev/md8e:     39600    ESP1 / SCSI3    Okay
 /dev/md0f:     /dev/md4f:     39600    ESP0 / SCSI3    Okay
                /dev/md8f:     39600    ESP1 / SCSI3    Okay
 /dev/md0g:     /dev/md4g:    306000    ESP0 / SCSI3    Okay
                /dev/md8g:    306000    ESP1 / SCSI3    Nds_Maint
 /dev/md0h:     /dev/md4h:    371520    ESP0 / SCSI3    Okay
                /dev/md8h:    371520    ESP1 / SCSI3    Okay

Operation SUCCEEDED

Note:  The md0g or /usr partition on the esp1 scsi bus has a status of
Nds_Maint.
          Use metadetach   -f   [Metamirror]
[Submirror_that_Nds_Maint]

21AP50# metadetach -f /dev/md0g /dev/md8g
Metadevice /dev/md8g is detached.

Note: Now run metattach int the background to attach and re-sync the
submirror.

21AP50# metattach /dev/md0g /dev/md8g &
[1] 838

Note: Executing multiple dft show_status commands will show the
progression
of the re-sync process. The final status should reflect a state of Okay
if
no errors were encountered.

21AP50# dft show_status
