Booting off an alternate disk partition
807557Jun 16 2008 — edited Jun 17 2008Hi All,
I am attempting to boot my system of an alternative partition (slice 3). I am running Sol10 (11/06) with SVM to mirror the internal disks (c0t0d0 and c0t0d0) the root partition is on slice 0. The process I have followed is;
1) created a third mirror of the boot partition (metadevice d10) on c0t0d0s3
2) Once the 3rd miiror sync'd it was detached.
3) updated the vfstab on c0t0d0s3 to set the root mount point to /dev/dsk/c0t0d0s3
4) shut the machine down
5) setup a new boot device alias to point to c0t0d0s3 : /pci@780/pci@0/pci@9/scsi@0/disk@0,0:d
6) booted the server.
The boot process progresses as i would expect - it boots off slice 3.
Boot device: /pci@780/pci@0/pci@9/scsi@0/disk@0,0:d File and args:
Loading ufs-file-system package 1.4 04 Aug 1995 13:02:54.
FCode UFS Reader 1.12 00/07/17 15:48:16.
Loading: /platform/SUNW,Sun-Fire-T200/ufsboot
Loading: /platform/sun4v/ufsboot
However, when the boot process completes, the o/s is running for d10 - the original system mount point as can be seen by the following output;
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d10 9.8G 5.1G 4.7G 52% /
Any pointers to the steps I have missed would be greatly appreciated.
