AIX

Hello everyone

I new aix 6.1 in a new partition. There is something new that I need to configure.

I saw two new filesystems

/dev/hd11admin 256.00 255.62 1% 5 1% /admin
/dev/livedump 256.00 255.64 1% 4 1% /var/adm/ras/livedump

Do you know the reason for this one.

I would like to hear your tips, opinions for this new version of Aix


Thanks

We've been running AIX 6.1 for about 3 months now. We have had good luck with it. The most convenient thing for us so far has been having nmon integrated with topas (use "~" to switch between the two different modes) and having it included with AIX instead of an extra install.

As far as the /var/adm/ras/livedump, it has to do with live dumps that AIX 6.1 can do. For some reason, it is created as a JFS filesystems. After the install, I went in and changed it to JFS2 because we just got through with a project to convert all our JFS filesystems over to JFS2.

kah00na, Does the live dump function still work OK on the JFS2 FS, or was this something you did for a laugh that will come back and haunt you in the future?

As for hd11admin:

Beginning with AIX V6.1 the operating system provides a dedicated system
directory /admin/tmp where privileged processes can securely create temporary
files. The /admin/tmp directory resides within the /admin file system which in turn
is defined on the newly implemented /dev/hd11admin system logical volume. You
can use the standard ls, lsfs, and lslv AIX commands to list the properties of
the directory, mount point, file system, and logical volume respectively

/var/adm/ras/livedump can be changed to JFS2 without any problems. Per IBM support:
