JFS2 log error during TL upgrade
Hi all,

We recently applied TL on few of our test servers. All of them were running fine except on one server. TL upgrade was successful on all these servers.

i see below errors on a server.

Code:
LABEL:          J2_LOG_WRAP_STOP
IDENTIFIER:     854D3B24

Date/Time:       Thu Jun  3 10:25:04 EDT 2014
Sequence Number:  
Machine Id:      xxx
Node Id:         aixlpar1
Class:           O
Type:            INFO
WPAR:            Global
Resource Name:   SYSJ2

Description
JFS2 LOGGING IS BACK TO NORMAL

LABEL:          J2_LOG_WRAP_START
IDENTIFIER:     4C41C0D0

Date/Time:       Thu Jun  3 10:24:39 EDT 2014
Sequence Number:  
Machine Id:      xxxxxxxx
Node Id:         aixlpar1
Class:           O
Type:            INFO
WPAR:            Global
Resource Name:   SYSJ2

Description
JFS2 LOG RECORDS FORCED OVERWRITTEN

Probable Causes
LOG SIZE IS TOO SMALL

        Recommended Actions
        INCREASE THE SIZE OF LOG DEVICE

Detail Data
JFS2 LOG MAJOR/MINOR DEVICE NUMBER
000A 0003

I understand that, it is because we do not have enough space on jfs2log lv.
because the (rootvg) pp size is only 8 MB on this server.

hd8 jfs2log 1 1 1 open/syncd N/A

#lsvg rootvg | grep "PP SIZE"
VG STATE: active PP SIZE: 8 megabyte(s)

i found the procedure to increase jfs2log size using IBM tech note below
IBM Increasing the Size of a JFS/JFS2 Log Device - United States


But here my question is,

do i still need to increase the size jfs2log size ?
because the info messgae on errpt says

JFS2 LOGGING IS BACK TO NORMAL

is there any procedure to increase the jfs2log size on the fly (dynamically). with out bringing the server ?

The above link says, we need to boot the server into service mode and run logform etc .


Please suggest.
