This document provides the procedure to add Logzilla to an "existing" pool on a Sun ZFS 7000 storage

Steps:

From BUI:

1. Go to "Configuration > Storage" .

From the list of available pool press "Add" corresponding to the pool where you want to add new disk.

Add Logzilla

2. Next screen will be "Verify and add devices"

Here you need to select the number of disks.

For the purpose of adding Logzilla select Data=0, LOG=n .

You can select CACHE=m incase you want to add cache disk.

where n,m is the number of disks.

And press "Commit" to accept the changes.

select number of disks

3. Selet the profile

For Logzilla you can select Log Profile as Striper or Mirror and commit the changes.

From CLI:

7000:configuration storage> add

7000:configuration storage verify> get

0 = custom
0-cache = 2
1 = custom
1-data = 18
1-log = 2
2 = custom
2-data = 24

7000:configuration storage verify> set 0-cache=0
0-cache = 0
7000:configuration storage verify> set 1-data=0
1-data = 0
7000:configuration storage verify> set 2-data=0
2-data = 0
7000:configuration storage verify> set 1-log=2
1-log = 2

7000:configuration storage verify> get

0 = custom
0-cache = 0
1 = custom
1-data = 0
1-log = 2
2 = custom
2-data = 0

7000:configuration storage verify> done

Check the Log Profile and change it if needed:

7000:configuration storage config> show

PROFILE CAPCTY NSPF DESCRIPTION
log_profile = log_mirror 17G no Mirrored log
log_stripe 34G no Striped log

log_profile will be set to a default optimal value depending on the number of disks selected.

But you can change the profile using set command in CLI to log_stripe or log_mirror

7000:configuration storage config> done

7000:configuration storage> show
Properties:
pool = M1
status = online
owner = 7000
profile = mirror
log_profile = log_mirror
cache_profile = -
scrub = none requested

Note:
Please note once the Logzilla is added to the pool it cannot be removed.
Just in case you need to remove logzilla from a pool you should contact Oracle Support
