Dear Candy, This is the log of zpool status, along with partition of c3d0 and c4d0
1. It appears to me that once I destroy the partition of c4d0 and recreate it again, I get different "slices" in c4d0. I forgot which fdisk partition I chose, it is either Solaris, Solaris2, or Unix System, and it gives the default location like that I think I must manually create slice, but If I look at c3d0, which slice should I mirror ? root ? backup ? 2. And, for mirror to works, does it have to reside in the same cylinder in the other disk ? 3. For mirroring an IDE device ( since this SATA drive is translated into IDE, which is visible if we see in "format" ), Is it correct that it have to be slice that is being mirrored, and can't be the whole disk like what I did in Fedora 10, using software raid at the installation time ? Thank you for everyone's guidance =============================================================== hando...@opensolaris:~# zpool status pool: rpool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c3d0s0 ONLINE 0 0 0 errors: No known data errors hando...@opensolaris:~# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c3d0 <DEFAULT cyl 60797 alt 2 hd 255 sec 63> /p...@0,0/pci-...@1f,2/i...@0/c...@0,0 1. c4d0 <SATA2 cyl 60797 alt 2 hd 255 sec 63> /p...@0,0/pci-...@1f,2/i...@1/c...@0,0 Specify disk (enter its number): 1 selecting c4d0 Controller working list found [disk formatted, defect list found] FORMAT MENU: disk - select a disk type - select (define) a disk type partition - select (define) a partition table current - describe the current disk format - format and analyze the disk fdisk - run the fdisk program repair - repair a defective sector show - translate a disk address label - write label to the disk analyze - surface analysis defect - defect list management backup - search for backup labels verify - read and display labels save - save new disk/partition definitions volname - set 8-character volume name !<cmd> - execute <cmd>, then return quit format> partition PARTITION MENU: 0 - change `0' partition 1 - change `1' partition 2 - change `2' partition 3 - change `3' partition 4 - change `4' partition 5 - change `5' partition 6 - change `6' partition 7 - change `7' partition select - select a predefined table modify - modify a predefined partition table name - name the current table print - display the current table label - write partition map and label to the disk !<cmd> - execute <cmd>, then return quit partition> print Current partition table (original): Total disk cylinders available: 60797 + 2 (reserved cylinders) Part Tag Flag Cylinders Size Blocks 0 unassigned wm 0 0 (0/0/0) 0 1 unassigned wm 0 0 (0/0/0) 0 2 backup wu 0 - 60796 465.73GB (60797/0/0) 976703805 3 unassigned wm 0 0 (0/0/0) 0 4 unassigned wm 0 0 (0/0/0) 0 5 unassigned wm 0 0 (0/0/0) 0 6 unassigned wm 0 0 (0/0/0) 0 7 unassigned wm 0 0 (0/0/0) 0 8 boot wu 0 - 0 7.84MB (1/0/0) 16065 9 alternates wm 1 - 2 15.69MB (2/0/0) 32130 format> disk AVAILABLE DISK SELECTIONS: 0. c3d0 <DEFAULT cyl 60797 alt 2 hd 255 sec 63> /p...@0,0/pci-...@1f,2/i...@0/c...@0,0 1. c4d0 <SATA2 cyl 60797 alt 2 hd 255 sec 63> /p...@0,0/pci-...@1f,2/i...@1/c...@0,0 Specify disk (enter its number)[1]: 0 selecting c3d0 NO Alt slice No defect list found [disk formatted, no defect list found] /dev/dsk/c3d0s0 is part of active ZFS pool rpool.
