Disk Mirroring

All,

I have a 4 way E450 running Solaris 8. To keep costs down we decided against
mirroring any of the disks on the machine but now I have been asked to
investigate the possibility of mirroring the key partitions on the server as
listed below.

/dev/dsk/c0t0d0s0 241219 154316 62782 72% /
/dev/dsk/c0t0d0s6 1185931 987968 138667 88% /usr
/dev/dsk/c0t0d0s5 1599623 954475 597160 62% /var

These are standard ufs partitions located on disk 0.

As the partitions stand will I be in a position to set up a mirror ? - if so
I presume additional software will be required.

Please can people advise as to what is the simplest way to achieve my
objective here.

I've not had anything to do with mirroring before on Solaris so apologies
for the basic questions.

Regards,
Mike.
