I have Solaris machine With two disks (the disks defined as RAID 1 (mirror configuration ) actually when I pull out one disk the second disk will be active

The problem is that when I run metadb on my Solaris machine I see only one disk - /dev/dsk/c1t0d0s7 in place to see two see two disks ?

Mirroring of the initial hard drive is taken place to the second hard drive.remark - However – if the first hard drive fails – the mirroring is useless since the replica information is not added for the second hard drive.

please advice how to add the second disk ?

    [root@solaris1a /]# metadb
    flags           first blk       block count
    a m  p  luo        16              8192            /dev/dsk/c1t0d0s7
    a    p  luo        8208            8192            /dev/dsk/c1t0d0s7
    a    p  luo        16400           8192            /dev/dsk/c1t0d0s7

You have to tell metadb explicitly what slices to use for its meta data. This

# metadb -a -c 2 c1t1d0s7

will place two more copies of the metadb into slice /dev/dsk/c1t1d0s7.
