1. First we should be sure have two identical harddisks in the server<\/p>\n

 # format\r\n Searching for disks...done\r\n AVAILABLE DISK SELECTIONS:\r\n       0. c0d0 <DEFAULT cyl 1563 alt 2 hd 255 sec 63>\r\n          \/pci@0,0\/pci-ide@7,1\/ide@0\/cmdk@0,0\r\n       1. c0d1 <DEFAULT cyl 1563 alt 2 hd 255 sec 63>\r\n          \/pci@0,0\/pci-ide@7,1\/ide@0\/cmdk@1,0\r\n Specify disk (enter its number): ^C<\/pre>\n
2. Its need to create small slice for metadb information (usually slice 7)
\nlike:<\/p>\n
   partition> p\r\n Current partition table (unnamed):\r\n Total disk cylinders available: 1563 + 2 (reserved cylinders)\r\n\r\n Part      Tag    Flag     Cylinders        Size            Blocks\r\n   0       root    wm     518 - 1562        8.01GB    (1045\/0\/0) 16787925\r\n   1       swap    wu       3 -  133        1.00GB    (131\/0\/0)   2104515\r\n   2     backup    wm       0 - 1562       11.97GB    (1563\/0\/0) 25109595\r\n   3 unassigned    wm       0               0         (0\/0\/0)           0\r\n   4 unassigned    wm       0               0         (0\/0\/0)           0\r\n   5 unassigned    wm       0               0         (0\/0\/0)           0\r\n   6 unassigned    wm       0               0         (0\/0\/0)           0\r\n   7 unassigned    wm     134 -  135       15.69MB    (2\/0\/0)       32130\r\n   8       boot    wu       0 -    0        7.84MB    (1\/0\/0)       16065\r\n   9 alternates    wu       1 -    2       15.69MB    (2\/0\/0)       32130<\/pre>\n
3. Next step is to create the same partitions on the second disk. To avoid
\nhuman error it is much better to use some kind of automations:<\/p>\n
 prtvtoc \/dev\/rdsk\/c0d0s2 > \/tmp\/c0d0s2.toc\r\n fmthard -s \/tmp\/c0d0s2.toc \/dev\/rdsk\/c0d1s2<\/pre>\n
4. Then we should identify the partitions need to be mirrored:<\/p>\n
 # egrep \"ufs|swap\" \/etc\/vfstab|grep \"\/dev\/dsk\"\r\n \/dev\/dsk\/c0d0s1 -       -       swap    -       no      -\r\n \/dev\/dsk\/c0d0s0 \/dev\/rdsk\/c0d0s0        \/       ufs     1       no      -<\/pre>\n
<\/a><\/p>\n
LVM<\/h2>\n
1. Let\u2019s create few copies of metadb on the partitions we create for this
\npuspose:<\/p>\n
 # metadb -a -f -c 2 c0d0s7 c0d1s7<\/pre>\n
2. It\u2019s time to put our disks where OS reside under management of SVM<\/p>\n
 # metainit -f d10 1 1 c0d0s0\r\n d10: Concat\/Stripe is setup\r\n # metainit -f d11 1 1 c0d0s1\r\n d11: Concat\/Stripe is setup\r\n # metainit d0 -m d10\r\n d0: Mirror is setup\r\n # metainit d1 -m d11\r\n d1: Mirror is setup\r\n # metaroot d0 \r\n # echo \"set md:mirrored_root_flag=1\" >> \/etc\/system<\/pre>\n
3. Check newly created devices:<\/p>\n
 # ls -l \/dev\/md\/rdsk\r\n total 8\r\n lrwxrwxrwx   1 root     root          36 Aug 30 18:29 d0 -> ..\/..\/..\/devices\/pseudo\/md@0:0,0,raw\r\n lrwxrwxrwx   1 root     root          36 Aug 30 18:29 d1 -> ..\/..\/..\/devices\/pseudo\/md@0:0,1,raw\r\n lrwxrwxrwx   1 root     root          37 Aug 30 18:28 d10 -> ..\/..\/..\/devices\/pseudo\/md@0:0,10,raw\r\n lrwxrwxrwx   1 root     root          37 Aug 30 18:28 d11 -> ..\/..\/..\/devices\/pseudo\/md@0:0,11,raw\r\n # ls -l \/dev\/md\/dsk\r\n total 8\r\n lrwxrwxrwx   1 root     root          36 Aug 30 18:29 d0 -> ..\/..\/..\/devices\/pseudo\/md@0:0,0,blk\r\n lrwxrwxrwx   1 root     root          36 Aug 30 18:29 d1 -> ..\/..\/..\/devices\/pseudo\/md@0:0,1,blk\r\n lrwxrwxrwx   1 root     root          37 Aug 30 18:28 d10 -> ..\/..\/..\/devices\/pseudo\/md@0:0,10,blk\r\n lrwxrwxrwx   1 root     root          37 Aug 30 18:28 d11 -> ..\/..\/..\/devices\/pseudo\/md@0:0,11,blk<\/pre>\n
4. Make appropriate changes in \/etc\/vfstab to get boot from mirror, not
\nstandard disks<\/p>\n
 # egrep \"ufs|swap\" \/etc\/vfstab|grep \"\/dev\/md\/dsk\"\r\n \/dev\/md\/dsk\/d1  -       -       swap    -       no      -\r\n \/dev\/md\/dsk\/d0  \/dev\/md\/rdsk\/d0 \/       ufs     1       no      -<\/pre>\n
5. The next step is to flush cache buffers and reboot<\/p>\n
 # sync;sync;sync\r\n # reboot<\/pre>\n
6. It is time to put second disk under management of SVN<\/p>\n
 # metainit -f d20 1 1 c0d1s0\r\n d20: Concat\/Stripe is setup\r\n # metainit -f d21 1 1 c0d1s1\r\n d21: Concat\/Stripe is setup<\/pre>\n
7. And to add them to created previously mirrors. Be aware process of
\nsynchronisation will continue in background and you can check the process<\/p>\n
 # metattach d0 d20\r\n d0: submirror d20 is attached\r\n # metattach d1 d21\r\n d1: submirror d21 is attached<\/pre>\n
8. Check the process of building mirrors and wait till they finnish<\/p>\n
 # metastat\r\n d1: Mirror\r\n     Submirror 0: d11\r\n       State: Okay\r\n     Submirror 1: d21\r\n       State: Resyncing\r\n     Resync in progress: 96 % done\r\n     Pass: 1\r\n     Read option: roundrobin (default)\r\n     Write option: parallel (default)\r\n     Size: 2104515 blocks (1.0 GB) \r\n\r\n d11: Submirror of d1\r\n     State: Okay\r\n     Size: 2104515 blocks (1.0 GB)\r\n     Stripe 0:\r\n         Device   Start Block  Dbase        State Reloc Hot Spare\r\n         c0d0s1          0     No            Okay   Yes \r\n\r\n\r\n d21: Submirror of d1\r\n     State: Resyncing\r\n     Size: 2104515 blocks (1.0 GB)\r\n     Stripe 0:\r\n         Device   Start Block  Dbase        State Reloc Hot Spare\r\n         c0d1s1          0     No            Okay   Yes\r\n \r\n\r\n d0: Mirror\r\n     Submirror 0: d10\r\n       State: Okay\r\n     Submirror 1: d20\r\n       State: Resyncing\r\n     Resync in progress: 13 % done\r\n     Pass: 1\r\n     Read option: roundrobin (default)\r\n     Write option: parallel (default)\r\n     Size: 16787925 blocks (8.0 GB) \r\n\r\n d10: Submirror of d0\r\n     State: Okay\r\n     Size: 16787925 blocks (8.0 GB)\r\n     Stripe 0:\r\n         Device   Start Block  Dbase        State Reloc Hot Spare\r\n         c0d0s0          0     No            Okay   Yes\r\n\r\n\r\n d20: Submirror of d0\r\n     State: Resyncing\r\n     Size: 16787925 blocks (8.0 GB)\r\n     Stripe 0:\r\n         Device   Start Block  Dbase        State Reloc Hot Spare\r\n         c0d1s0          0     No            Okay   Yes\r\n\r\n\r\n Device Relocation Information:\r\n Device   Reloc  Device ID\r\n c0d1   Yes      id1,cmdk@AVMware_Virtual_IDE_Hard_Drive=01000000000000000001\r\n c0d0   Yes      id1,cmdk@AVMware_Virtual_IDE_Hard_Drive=00000000000000000001<\/pre>\n
<\/a><\/p>\n
Boot<\/h2>\n
1. Next step is to check if partition on second disk is active<\/p>\n
 # fdisk \/dev\/rdsk\/c0d1p0\r\n             Total disk size is 1566 cylinders\r\n             Cylinder size is 16065 (512 byte) blocks\r\n\r\n                                               Cylinders\r\n      Partition   Status    Type          Start   End   Length    %\r\n      =========   ======    ============  =====   ===   ======   ===\r\n          1       Active    Solaris2          1  1565    1565    100\r\n\r\n\r\n SELECT ONE OF THE FOLLOWING:\r\n    1. Create a partition\r\n    2. Specify the active partition\r\n    3. Delete a partition\r\n    4. Change between Solaris and Solaris2 Partition IDs\r\n    5. Exit (update disk configuration and exit)\r\n    6. Cancel (exit without updating disk configuration)\r\n Enter Selection: 5<\/pre>\n
2. And to add boot record to the second disk to make it bootable<\/p>\n
 # \/sbin\/installgrub \/boot\/grub\/stage1 \/boot\/grub\/stage2 \/dev\/rdsk\/c0d1s0\r\n stage1 written to partition 0 sector 0 (abs 16065)\r\n stage2 written to partition 0, 233 sectors starting at 50 (abs 16115)<\/pre>\n
3. Add new item in the boot menu (\/boot\/grub\/menu.lst) to have alternative
\nway to boot<\/p>\n
# vi \/boot\/grub\/menu.lst \u6dfb\u52a0\u4ee5\u4e0b\u5185\u5bb9\uff1a<\/p>\n
 title Alternate boot\r\n root (hd1,0,a)\r\n kernel \/platform\/i86pc\/multiboot\r\n module \/platform\/i86pc\/boot_archive<\/pre>\n
4. Check if the new item is added to the boot menu<\/p>\n
 # bootadm list-menu\r\n The location for the active GRUB menu is: \/boot\/grub\/menu.lst\r\n default 0\r\n timeout 10\r\n 0 Solaris 10 5\/08 s10x_u5wos_10 X86\r\n 1 Solaris failsafe\r\n 2 Alternate boot<\/pre>\n
5. That\u2019s all, you have already mirrored root partition (plus swap)<\/p>\n","protected":false},"excerpt":{"rendered":"
