Convert rootvg file systems to JFS2 using alt_disk_copy
Q: Does
alt_disk_copy convert JFS filesystems to JFS2? A: Yes! Starting at 6100-04 , a new
flag was introduced that would convert JFS filesystems to JFS2. We now have the
-T which does the conversion. http://www-01.ibm.com/support/docview.wss?uid=isg3T1011055 Here’s an example of converting
rootvg file systems from JFS to JFS2 using alt_disk_copy .
My lab system was migrated from AIX
5.3 to 7.1 via nimadm . Unfortunately, nimadm does not convert JFS file
systems to JFS2 during the migration. So, in this case, even though... [More]

Working with AIX scalable volume groups - Part 2 - converting to scalable.
Following on
from my previous post, on working with scalable VGs. https://www.ibm.com/developerworks/mydeveloperworks/blogs/cgaix/entry/working_with_aix_scalable_volume_groups1?lang=en You may find
yourself in a situation where you’d like to convert a VG to scalable. For example,
you might start off with a normal VG i.e. one that can support a maximum of 256
LVs and 32 PVs. # mkvg -s
512M -y myvg hdisk5 myvg # lsvg myvg VOLUME
GROUP: myvg VG IDENTIFIER: 00f6027300004c0000000133aa24d1f6 VG

Convert rootvg JFS file systems to JFS2 with alt_disk_copy
Starting with AIX 6.1 (TL4?), you can use the alt_disk_copy command to convert rootvg
file systems from jfs to jfs2. The man page for the alt_disk_copy command
states the following: -T
Indicates that you want to convert JFS file systems to JFS2 file systems during
the process of recreating the rootvg volume group on target disks. As an example, to clone a running systems rootvg to hdisk2, and convert
the rootvg file systems from JFS to JFS2, you would run the following command: #
alt_disk_copy -T -d hdisk2 Good to know!
