Just add the other disk to the system, and then in NRM click on the new
disk to initialize it; then click on the original disk's mirroring link.
You should get a page showing free space on the new disk, and you click on
that to add it to the mirror.

That said, I think NSSMU is the better tool for mirroring.

Re: Mirror question in NRM

The first disk still have status being mirrored. So when i click on the
mirrored status, it shows the previous virtual partitions. For the new
disk, i create a new pool ? Thasnks

No, no pool.

I recommend that you use NSSMU.

1) load NSSMU

2) Select RAID devices

3) Select the RAID (mirror) set of interest

4) Select the "offline" partition

5) Press the DELETE key

6) You now have a "complete" mirror, even if it only has 1 partition in it.

Now install the new disk; this may require you to power down the system
and reboot afterwards (IDE drives usually aren't hot swap).

When you are back up, use NSSMU again:

1) load NSSMU

2) Select DEVICES

3) Press F3 to initialize the new disk

4) return to top level menu and select RAID devices

5) select the partition of interest

6) Press F3 to expand the mirror

7) Select the new device

😎 Press F5 occasionally if you want to see the mirror percentage update,
otherwise exit.

Re: Mirror question in NRM

Hi, doesn't matter if NRM shows first disk is still mirrored if i use
NSSMU ? but i feel that NRM is more user friendly.

No, because the first part of my instructions clean that up.

Sure -- it's meant to be. But it isn't as flexible. And I've had
experiences with it deleting the partition I was trying keep rather than
the missing partition.

NSSMU isn't very tough to use.

Re: Mirror question in NRM


Dave, if my 1st disk is a new installation(not mirrored and restore as
master disk) and i want to make a new mirror then i just follow the 2nd
part of your instructions ? Thanks

To clean up the old mirroring status.

Is that after doing the cleanup in NSSMU? Then I guess it is because the
partition has the mirrored attribute for ever and ever, and that NRM sees
that, and doesn't check to see if count=1.

Re: Mirror question in NRM

Now the problem is that the 2nd disk i have make a bootable dos partiton
earlier and if i do init disk (f3) in NSSMU , it will delete all and make
a new partition table then i would loss the dos partition. So how to
retain that partition ? Thanks

F3 isn't required if you already have a partition table.

Re: Mirror question in NRM

Hi thanks it works. Very fast compared to NRM. But why do you say it is
more flxeible ? in terms of what ?

Well, I find it very easy to have more than 2 RAID segments for a given
mirror -- if I use NSSMU. NRM assumes you will only use 2.

I use this trick to have a "cold spare" of my sys, since I often do things
that damage the volumes/pool/partition data structures. Make a 3-way
mirror, pull 1 RAID segment, cleanup to 2 segments and reboot. Do my
tests, scramble partition. Pull damaged copies, plug in spare, reboot and
re-expand the mirror.
