Reply to: SUMMARY: LSM, AdvFS and Mirroring
Thanks for the friendly reply from Sam Sarasin, who knew just what I
was trying to do, even with my reversed understanding. The LSM manual
spends many pages on encapsulation, and that threw me. The original
question phrased differently was basically how to make an advfs domain
be mirrored using LSM. Thanks also to Jean-Pierre Lamarche who offered
a similar solution.

Hello Dan,
I think I am following you. I like to use the GUI to do what you have
shown it makes it a snap.
First use dxlsm to create a volume. Make sure you do not select the
option
to make a UFS file system.
+================+
| vol01 |
|----------------|
| +-------------+|
| | plex01 ||
| |-------------||
| | rz25c ||
| |-------------||
| | rz26c ||
| +-------------+|
+================+
Then from the basic-ops menu select ADVFS-OPERATIONS this will launch
dxadvfs.
in dxadvfs select /dev/vol01 as the volume you wish to make a advfs
domain. Or
just use the command line and tell advfs you want a domain on
/dev/vol/rootdg/vol01
mkfdmn /dev/vol/rootdg/vol01 my_domain
Then make your file sets and mount them. One thing to note dxlsm will
not
currently show mounted ADVFS volumes like it shows UFS volumes with the
mount point shown under the volume.
+================+
| ADVFS |
|----------------|
| VOL01 |
|----------------|
| +-------------+|
| | plex01 ||
| |-------------||
| | rz25c ||
| |-------------||
| | rz26c ||
| +-------------+|
+================+
Next in dxlsm from the basic-ops menu select volume operations --> add
mirror.
It will create the plex and add it for you. If you like you can create
a plex by
hand and drag and drop it on the volume. That will also create a
mirror. What
you will then see is this.
+=================================+
| ADVFS |
|---------------------------------|
| vol01 |
|---------------------------------|
|---------------------------------|
| +-------------+ +-------------+ |
| | plex01 | | plex02 | |
| |-------------| |-------------| |
| | rz25c | | rz27c | |
| |-------------| |-------------| |
| | rz26c | | rz29c | |
| +-------------+ +-------------+ |
+=================================+
I have added ADVFS to your picture to show where it fits in relation to
LSM.
I have tried the above on my system and had no problems.
If you have problems send me a note. I will be happy to give you a
call.
