My AIX is very rusty! Perhaps you should have used crfs, actually, with the -A yes option to automount the filesystem. Still, no worries. You can just copy-paste the previous entry into /etc/filesystem, changing the LV name and any other details as appropriate, and then mount the filesystem manually.

Code:

/data01:
        dev             = /dev/lv00
        vfs             = jfs2
        log             = /dev/loglv00
        mount           = true
        options         = rw
        account         = false

(I added the /, as I assume it's missing)

It's not clear where lvdata01 came from. Did you just create that too?

If the filesystem /data01 is for database data, you might consider adding noatime to the options.
