Thank you Scott! I created a new logical volume from my volume group data01, like you said:
Code:
[root@ibm: dev]# mklv data01 65G
lv00
[root@ibm: dev]# lslv lv00
LOGICAL VOLUME:     lv00                   VOLUME GROUP:   data01
LV IDENTIFIER:      00c3e63a00004c000000013535af9d5f.3 PERMISSION:     read/write
VG STATE:           active/complete        LV STATE:       closed/syncd
TYPE:               jfs                    WRITE VERIFY:   off
MAX LPs:            520                    PP SIZE:        128 megabyte(s)
COPIES:             1                      SCHED POLICY:   parallel
LPs:                520                    PPs:            520
STALE PPs:          0                      BB POLICY:      relocatable
INTER-POLICY:       minimum                RELOCATABLE:    yes
INTRA-POLICY:       middle                 UPPER BOUND:    32
MOUNT POINT:        N/A                    LABEL:          None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?:     NO

Then I tried to create the new filesystem:
Code:
[root@ibm: dev]# mkfs -V jfs2 -o name=/data01 /dev/lv00
mkfs: destroy /dev/lv00 (yes)? y
File system created successfully.
68155156 kilobytes total disk space.
Device /dev/lv00:
  Standard empty filesystem
  Mount point:    /data01
  Size:           136310312 512-byte (DEVBLKSIZE) blocks

However when I ran df my new filesystem did not show up:
Code:
[root@ibm: /]# df
Filesystem    512-blocks      Free %Used    Iused %Iused Mounted on
/dev/hd4       104857600  83368944   21%    11249     1% /
/dev/hd2         6815744    799104   89%    45470    33% /usr
/dev/hd9var      3407872   1133104   67%     8384     6% /var
/dev/hd3          262144      8624   97%      139     4% /tmp
/dev/fwdump       524288    523424    1%       19     1% /var/adm/ras/platform
/dev/hd1         1048576   1047616    1%        7     1% /home
/dev/hd11admin     262144    261384    1%        5     1% /admin
/proc                  -         -    -         -     -  /proc
/dev/hd10opt     2097152   1279616   39%    14927    10% /opt
/dev/livedump     524288    523552    1%        4     1% /var/adm/ras/livedump

Also my /etc/filesystems file does not have an entry for /data01.

Did I do something wrong? Was I supposed to set an auto-mount option or something?

When I look at the volume group information, my new logical volume shows up but it says N/A for mount point, was I supposed to do something when creating the new LV?
Code:
[root@ibm: /]# lsvg -l data01
data01:
LV NAME             TYPE       LPs     PPs     PVs  LV STATE      MOUNT POINT
lvdata01            jfs        1       1       1    closed/syncd  N/A
loglv00             jfs2log    1       1       1    closed/syncd  N/A
lv00                jfs        520     520     1    closed/syncd  N/A
