Solaris disksuite mirror


I just documented mine for Solaris 8. This is using Solstice Disk Suite. The drives are c1t0d0 and c1t1d0. Hope this helps.

Install Solstice disksuite from Solaris Software, disk 2 of 2.
#cd /cdrom/sol_8_202_sparc_2/Solaris_8/EA/products/DiskSuite_4.2.1
1. run ./installer
2. default install (place in /usr/sbin) and allow reboot
Run commands below:
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
(This causes the mirrored disk to have the exact format as the main root disk).
Run format and check that BOTH internal disks match exactly. If not, this will fail.

BOTH internal drives need to match exactly.

# metadb -a -f c1t0d0s7
# metadb -a c1t1d0s7
# metainit -f d10 1 1 c1t0d0s0
d10: Concat/Stripe is setup
# metainit -f d20 1 1 c1t1d0s0
d20: Concat/Stripe is setup
# metainit d0 -m d10
d0: Mirror is setup
# metaroot d0
# metainit -f d11 1 1 c1t0d0s1
d11: Concat/Stripe is setup
# metainit -f d21 1 1 c1t1d0s1
d21: Concat/Stripe is setup
# metainit -f d13 1 1 c1t0d0s3
d13: Concat/Stripe is setup
# metainit -f d23 1 1 c1t1d0s3
d23: Concat/Stripe is setup
# metainit d1 -m d11
d1: Mirror is setup
# metainit d3 -m d13
d3: Mirror is setup
# metainit -f d14 1 1 c1t0d0s4
d14: Concat/Stripe is setup
# metainit -f d24 1 1 c1t1d0s4
d24: Concat/Stripe is setup
# metainit d4 -m d14
d4: Mirror is setup
# metainit -f d15 1 1 c1t0d0s5
d15: Concat/Stripe is setup
# metainit -f d25 1 1 c1t1d0s5
d25: Concat/Stripe is setup
# metainit d5 -m d15
d5: Mirror is setup
# metainit -f d16 1 1 c1t0d0s6
d16: Concat/Stripe is setup
# metainit -f d26 1 1 c1t1d0s6
d26: Concat/Stripe is setup
# metainit d6 -m d16
d6: Mirror is setup

# echo “set md:mirrored_root_flag=1” >> /etc/system

edit /etc/vfstab. Use the /dev/md/dsk/d0 (or 1/3/4/5/6) instead of c1t0d0s0 (or 1/3/4/5/6)
reboot

run following commands:
# metattach d0 d20
d0: submirror d20 is attached
# metattach d1 d21
d1: submirror d21 is attached
# metattach d3 d23
d3: submirror d23 is attached
# metattach d4 d24
d4: submirror d24 is attached
# metattach d5 d25
d5: submirror d25 is attached
# metattach d6 d26
d6: submirror d25 is attached

Check progress of mirror sync. The mirroring takes 2-3 hours.
# metastat|grep -i progress

While waiting, run metastat -p | tee /etc/lvm/md.tab (captures DiskSuite config)

Then run # dumpadm -d /dev/md/dsk/d1

update-metainit

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME

       update-metainit - Generates init scripts

SYNOPSIS

       update-metainit [--remove initname [--purge] ]

DESCRIPTION

       Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
       declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
       trator.

       If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
       a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
       effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.

OPTIONS

       --remove initname
	   This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.

       --purge
	   Only usable with --remove. Will remove the generated files even if modified.
