TSM: Enabling logging of TSM server service on Windows

Question

Is there any logging to check what the server is doing when starting the server as a service?

Cause

When starting the Tivoli Storage Manager server in the foreground using dsmserv command, there are logging information in the command windows to see what actions the server is taking. However, if the server is started using the Windows service, there is no logging information. This is especially helpful when debuging problems in regard to the service failing to start.

Google does redirect of blogger sites to a country-specific URL (ccTLD)

In last days I noticed that Google redirects my blog from address radek-it.blogspot.com to radek-it.blogspot.cz.

I googled today to know the reason of doing that and here is the explanation:

http://support.google.com/blogger/bin/answer.py?hl=en&answer=2402711

How can they do such change without noticing blog owners?
Yes, I know, it's for free but anyway I don't agree with this process and I'm considering to move blog from blogger to own web hosting with another blogging application.

Estimating deduplication on a TSM server database and storage pools

Determining the impact of deduplication on a Tivoli Storage Manager server database and storage pools

How can I tell how much Tivoli Storage Manager server database space is being consumed to manage my deduplicated storage pools? How much data am I saving in my deduplicated storage pools? If my server continues to manage more and more data, how much growth can I expect within my database? This document addresses these questions from a cost-benefit angle.

PowerVM: Managing VLANs on SEA on-line without any disruption

Make VLAN tagging modular to avoid downtime

Summary:  Shared Ethernet adapters (SEAs) can be used for IEEE 802.1Q VLAN tagging. However, once the SEA is in use, you cannot make changes to the VLANs on the trunk virtual Ethernet adapter without stopping the SEA. By using separate virtual adapters for each tagged VLAN, you can attach a new virtual adapter with its new VLAN to the SEA without any downtime. Retiring a VLAN from the SEA can be just as easy with a modular approach: one tagged VLAN per virtual adapter.

The problem and goal:

You have a shared Ethernet adapter (SEA) with VLAN tagging that services mission-critical websites. A new website requires an additional VLAN to be attached to the SEA. Outages are difficult to arrange. You can not use dynamic logical partitioning (DLPAR) to add VLANs to an existing virtual adapter on the SEA, because the adapter is in use as part of the SEA configuration.

H205535: Possibility of incorrect data being written on Multi-bit error correcting code (ECC) - IBM System Storage


Source

RETAIN tip: H205535
http://www-947.ibm.com/support/entry/portal/docdisplay?brand=5000008&lndocid=MIGR-5090005

Symptom

When one of the listed IBM Storage Subsystem controllers has detected a Multi-bit Error Correcting Code (ECC) memory error, users will see an informational message in the Major Events Log (event 0x2604) and that individual controller will reboot. If that Multi-bit ECC memory error happens on a dirty cache block that does not begin at offset 0x0, the data may be written incorrectly.
Any of the listed IBM Storage Subsystem controllers running any of these controller firmware versions are susceptible to this issue.
  • 7.77.33.00 or older
  • 7.70.45.00 or older
  • any 7.60.xx.xx
  • any 7.50.xx.xx
  • any 7.36.xx.xx
  • 7.35.69.00 or older
  • any 7.30.xx.xx

How to track allocated resource in NIM, reset and deallocate resouces

If a resource is allocated to any client in NIM and you want to delete or change resource you get this type of message:

lparx:/ # nim -o remove -arm_image=yes master_mksysb
0042-001 nim: processing error encountered on "master":
   0042-061 m_rmbosi: the "master_mksysb" resource is currently
        allocated for client use

To check whether resource is allocated:
lsnim -l -t mksysb | egrep ":|alloc_count"|grep -v date
lsnim -l -t lpp_source| egrep ":|alloc_count"|grep -v date
lsnim -l -t spot| egrep ":|alloc_count"|grep -v date

To reset and deallocate resources from all machines run this script:
for i in `lsnim -c machines | awk '{print $1}'`
do
    nim -o reset -a force=yes $i
    RC=$?
    if [ $RC -eq 0 ] ; then
        nim -Fo deallocate -a subclass=all $i
    fi
