oh my... As suspected, your slice 6 was not attached when your mirroring was done. SO now, since only the ONLY submirror which was working had failed, you will definitely loose all your data in slice 6 and will have to restore them. d26, the second submirror will not have the latest data that you had in the system before the primary disk failed.

metaonline
metaoffline(1M) System Administration Commands metaoffline(1M)
NAME
metaoffline, metaonline - place submirrors offline and online
SYNOPSIS
/usr/sbin/metaoffline -h
/usr/sbin/metaoffline [-s setname] [-f] mirror submirror
/usr/sbin/metaonline -h
/usr/sbin/metaonline [-s setname] mirror submirror
DESCRIPTION
The metaoffline command prevents Solaris Volume Manager from reading and writing to the submirror that has been taken offline. While the
submirror is offline, all writes to the mirror will be kept track of (by region) and will be written when the submirror is brought back
online. The metaoffline command can also be used to perform online backups: one submirror is taken offline and backed up while the mirror
remains accessible. (However, if this is a two-way mirror, data redundancy is lost while one submirror is offline.) The metaoffline command
differs from the metadetach command because it does not sever the logical association between the submirror and the mirror. To completely
remove a submirror from a mirror, use the metadetach command.
A submirror that has been taken offline will only remain offline until the metaonline command is invoked or the system is rebooted.
When the metaonline command is used, reading from and writing to the submirror resumes. A resync is automatically invoked to resync the
regions written while the submirror was offline. Writes are directed to the submirror during resync. Reads, however, will come from a dif-
ferent submirror. Once the resync operation completes, reads and writes are performed on that submirror. The metaonline command is only
effective on a submirror of a mirror that has been taken offline.
The metaoffline and metaonline commands can not be used on RAID 1 volumes in application-based recovery (ABR) mode.
A submirror that has been taken offline with the metaoffline command can only be mounted as read-only.
OPTIONS
Root privileges are required for all of the following options except -h.
-f Forces offlining of submirrors that have slices requiring maintenance.
-h Displays usage message.
-s setname Specifies the name of the diskset on which metaoffline and metaonline will work. Using the -s option will cause the com-
mand to perform its administrative function within the specified diskset. Without this option, the command will perform
its function on local metadevices.
mirror Specifies the metadevice name of the mirror from which the submirror will be either taken offline or put online.
submirror Specifies the metadevice name of the submirror to be either taken offline or put online.
EXAMPLES
Example 1: Taking a Submirror Offline
This example takes one submirror, d9, offline from mirror d10.
# metaoffline d10 d9
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
