Dear All,
We are using one pair of mirrored hard disk connected with AW51E. Today we
shutdown our AW and then disconnected the two hard disks for AW service.
When we restarted AW with the mirrored hard disk reconnected, it prompted
Nds_Maint errors for mirrored hard disk. To resolve this problem I used
metadetach and metattach commands as recommended by Invensys. I first used
metadetach for d0 and d20, it detached the d20 successfully but when I
executed metattach to reattach d0 and d20 it was not successful with the
following error messages.
# dft show_status
Metamirror Submirror Size Device State
d0: d10: 146072 ESP1 / SCSI0 Okay
d1: d11: 282720 ESP1 / SCSI0 Okay
d21: 282720 ESP2 / SCSI0 Nds_Maint
d2: d12: 94240 ESP1 / SCSI0 Okay
d22: 94240 ESP2 / SCSI0 Nds_Maint
d3: d13: 329840 ESP1 / SCSI0 Okay
d23: 329840 ESP2 / SCSI0 Nds_Maint
d4: d14: 2026160 ESP1 / SCSI0 Okay
d24: 2026160 ESP2 / SCSI0 Nds_Maint
d5: d15: 32479816 ESP1 / SCSI0 Okay
d25: 32479816 ESP2 / SCSI0 Nds_Maint
d20: 146072 ESP2 / SCSI0 Not Attached
Operation SUCCEEDED
# metattach d0 d20 &
1993
# metattach: 03AW02: /dev/md/rdsk/d20: No such device or address
#
Do any one have the idea of such problem and its solution?
Rgds,
Ali Ahmed Zahidi
