Setting up Boot Disks
You must encapsulate the boot disk for Sun StorEdge Volume Manager to be able to
mirror it. You are strongly recommended to do the following to ensure that the boot
disk is configured for the Netra ft 1800:
■ Assuming that A-DSK0 is the Solaris install disk, you should have entered the
command shown below at the end of the Solaris installation. See eeprom (1) for
details on using eeprom command to change the boot device.
■ Encapsulate the boot disk when the vxinstall process asks whether you want
to do so.
■ To mirror this root disk, add another disk, for example, b-dsk0, as a new disk.
See the Sun StorEdge Volume Manager Installation Guide for details of how to do
this during the vxinstall process.
The vxinstall process proposes the rootdg disk group by default. Accept this to
add the boot disk and disks intended to mirror the boot disk to this group.
When the vxinstall process is complete, use the vxdiskadm utility to make the
new disk a mirror of the boot disk, for example, make b-dsk0 a mirror of a-dsk0.
To start vxdiskadm:
Select option 6, Mirror volumes on a disk.
See the Sun StorEdge Volume Manager System Administrator’s Guide for full details of
using vxdiskadm.
Note – To assist recovery of data in the event of disk failure, use the boot disk only
for data required to boot the system. Do not add user-data disks to the rootdg
group.
