Regarding Sun volume manager

UNIX Solaris
1

hi all,
i have a doubt. I am doing some R & D in sun volume manager. Sun solaris 5.10 is running in my sun blade 150 sparc machine. I have attached ultrascsi storage box(6x36GB hdd's) with my machine. when i create a raid 0 striping or raid 1 mirroring the output of metastat says Dbase = No. Can anybody clarify this?
The sequence of my raid 0 stripe is as follows

bash-3.00# metadb -a c1t1d0s7 c1t2d0s7 c1t3d0s7
bash-3.00# metadb
        flags           first blk       block count
     a        u         16              8192            /dev/dsk/c1t1d0s7
     a        u         16              8192            /dev/dsk/c1t2d0s7
     a        u         16              8192            /dev/dsk/c1t3d0s7
bash-3.00# metainit d11 1 3 c1t1d0s0 c1t2d0s0 c1t3d0s0
d11: Concat/Stripe is setup
bash-3.00#
bash-3.00#
bash-3.00# metastat
d11: Concat/Stripe
    Size: 62919531 blocks (30 GB)
    Stripe 0: (interlace: 32 blocks)
        Device     Start Block  Dbase   Reloc
        c1t1d0s0          0     No      Yes
        c1t2d0s0          0     No      Yes
        c1t3d0s0          0     No      Yes

Device Relocation Information:
Device   Reloc  Device ID
c1t1d0   Yes    id1,sd@SFUJITSU_MAN3367M_SUN36G_02X79965____
c1t2d0   Yes    id1,sd@SFUJITSU_MAN3367M_SUN36G_02X81508____
c1t3d0   Yes    id1,sd@SFUJITSU_MAN3367M_SUN36G_02X86669____

So, why it shows Dbase = No when i have a valid metadatabases?

from the admin guide:

the metadbs are on other slices of your disks. so the dbase output says "no" for slice0 cause there are no state databases.

thanks for your clarification...in my book, the author created both state database replica and volume on same slice. Thats y it says dbase=yes. I was confused. Now i understood. Thanks
