I just found that , if I use add volume * command, system will add one more
volume to the existing ZFS file system having already 2 volume .

So, after this now ZFS will have 3 volume attached. After this, I should

If there are z13 models not listed in the earlier LSPR link, then why aren't

Again, the lowest z13 MSU I saw was about double what I need and on a bloody
