As you might have noticed I have not written that many articles of the last year. Reason is after 7 great years I left the AIX division of my company and moved forward, therefore not that much AIX stuff will be added to this blog in the future.
Expect to have new articles regarding SAP Installations and Monitoring SAP with Nagios.
To enable MKV on newly Twonky Releases with a Sony BD Player (or any other cartiva enabled device, you need to modify the .xml file
Sony_Blu-Ray_Player.xml in your twonkeyserver/devicedb folder.
Check that the feature of “additional picture size” is removed – final config should look like
POLL_AVT_STATE
BROKEN_SETNEXT
SUPPRESS_STATE_EVENTS
NEED_NO_PLAY_4_SETAVT
Have fun 🙂
Appareantly the No-ip update service does not work properly.
therefore I did some changes to the scripts:
/etc/init.d/ddns_update_for_cgi.sh
added line 66
/sbin/daemon_mgr noip2 stop /usr/sbin/noip2 1>/dev/null 2>/dev/null
/etc/init.d/check_ddns_external_ip.sh
uncomment lines:
#SEVER_TYPE=`grep “Server Type” ${DDNS_TMP_FILE} | /bin/tr -cs ‘[0-9\.]’ ’12’`
#if [ ${SEVER_TYPE} = 5 ]; then
# /bin/echo “no-ip don’t need use this functin”
# exit 0
#fi
seems to work now 🙂
Find within this entry a ganglia setup I just created today after reading lots of different webpages.
The goal is to have 1 gmetad installation with only gmond serving the data.
Installation and design is for IBM Powersystems, but should be adapted to any other platform.
This article is about “stuff you know” , “stuff you think you should know” and “stuff you dont know you dont know”.
It is personally about people realising to stop pushing them to know everything and ALL of their heads and get a bit more relaxed.

Today I installed HMC V7.7.6 SP1 and tried to connect IBM Blade p701 to it.
With given information that was an easy job (once you have all network config done), you just need to remember some stuff:
Guide on how to do the connection from IBM:

Also ASMI config for IBM blades:
If you need to change FC attributes try this little ‘one-liner’
for i in `lspv | awk '{print $1}'`; do chpath -l $i -s disable -p fscsi0;done
rmdev -l fcs0 -R
chdev -l fcs0 -a num_cmd_elems=2048
cfgmgr
chdev –l fcs0 –a max_xfer_size=0x200000 -P
for i in `lspv | awk '{print $1}'`; do chpath -l $i -s disable -p fscsi1;done
rmdev -l fcs1 -R

if [ “$varMem” -ne “0” ]
then
echo “$varSys $varLpar – removing Mem $varMem”
chhwres -r mem -m $varSys -o r -q $varMem -p $varLpar

Something that was used this morning as TSM died with logvolume being 100% used and no DB backup possible as library is offline.
Determining if the log is full
Start TSM (dsmserv) from the command line so that the startup messages can be seen. A message stating that log space cannot be allocated will be seen if the server is out of log space just prior to dsmserv dumping core.
So your log is full
From a command line on the TSM server, execute:
dsmfmt –m –log /tsmlog01/log911.tsm 1000
dsmserv extend log /tsmlog01/log911.tsm 1000
The log will be extended by 1000 meg. This is very little room (room=time) to fix the problem.
Start the TSM server in quiet mode. If TSM fails to start, see section Determining if the log is full.
From a TSM command prompt execute:
disable sessions
This command will stop ALL client activity.
TSM is up, now what?
Now that TSM is running, determine the cause of the log becoming full, most likely causes are no scratch tapes, no tape drives, and a large archive conversion. Remember, you only have 1000 megs of log space. (Q log f=d)
Now that everything is cool again
After the server is running normally, you must remove the 911 log file. Failure to do this will render the system unrecoverable should the log become full again.
1. Change the log mode to normal
2. Reduce the log size by 1000 meg – (REDUCE LOG 1000)
3. DELETE LOGVOLUME /tsmlog01/log911.tsm (the file is not deleted, just the TSM reference)
4. Change the log mode to Rollforward, this will cause a DB backup
5. From a TSM command line run: enable sessions
thanks to adsm.org for the procedure
Migrationg data (profile,network settings,etc) from one HMC to another can be done by following process:
1. Save data on current hmc with “upgrade data” via the menu or command line “saveupgdata -r diskdvd” to DVD-RAM
2. startup the new HMC and insert the DVD-RAM and transfer the upgrade data to the local disk via “mount /media/cdrom & rstupgdata -r dvd”
3. restart hmc
Done
