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]

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!

JFS2 logging disabled during mksysb restore.
While attending the IBM Power Systems
Symposium this week, I learnt that starting with AIX 7.1 (and AIX 6.1 TL6) JFS2
logging is disabled during a mksysb restore. You may be familiar with disabling
JFS2 logs, if not, take a look at this IBM technical note: https://www-304.ibm.com/support/docview.wss?uid=isg3T1012643 I’ve been unable to find any official
documentation from IBM that mentions this new enhancement to the mksysb restore
process. However, when I checked my own AIX 7.1 system I found the following
statement/code in the... [More]
