HSCLA27C, reserve_policy and LPM validation error.

cggibbo 270000TMUJ | | Comments (5) | Visits (18014)

Tweet
A customer was attempting to move an LPAR from one POWER7 750 to another POWER7 750 using Live Partition Mobility (LPM). But he was receiving the following error message when performing an LPM validation.     This was an easy one to fix. The reserve policy on the hdisk on the VIOS (yes, it was a single VIO server not dual VIOS, don’t ask why!) was set to PR_exclusive instead of no_reserve.   $ lsmap –vadapter vhost0 SVSA             Physloc                                       Client Partition ID...

Creating a CAA cluster on AIX 7.1.

cggibbo 270000TMUJ | | Visits (29955)

In this post I’ll demonstrate how to create a Cluster Aware AIX (CAA) cluster on AIX 7.1. I’ll create a simple two-node CAA cluster. I’ll then check the cluster status and, finally, remove the cluster.   Before I start, I make sure that both nodes have entries in /etc/hosts on both systems.   node1[/] > grep node /etc/hosts 172.29.134.169   node1 172.29.152.160   node2   node2[/] > grep node /etc/hosts 172.29.134.169   node1 172.29.152.160   node2   I verify that cluster services are not active on both nodes.   node1[/tmp/cg]...

JFS2 logging disabled during mksysb restore.

cggibbo 270000TMUJ | | Comment (1) | Visits (13729)

While attending the IBM Power Systems Symposium this week, I learnt that starting with AIX 7.1 (and AIX 6.1 TL6) JFS2 logging is disabled during a mksysb restore. You may be familiar with disabling JFS2 logs, if not, take a look at this IBM technical note:   https://www-304.ibm.com/support/docview.wss?uid=isg3T1012643   I’ve been unable to find any official documentation from IBM that mentions this new enhancement to the mksysb restore process. However, when I checked my own AIX 7.1 system I found the following statement/code in the... [More]

Querying the Cluster Aware AIX solidDB database.

cggibbo 270000TMUJ | | Visits (12849)

Did you know that you can connect to and query the new solidDB database used by Cluster Aware AIX (CAA)?   You can connect to the solidDB instance and issue SQL queries against the database. In the following example, I issued two queries: one to list the tables in the database and another to query information relating to the nodes in the cluster. The formatting in the second query is a mess, but you get the idea.   root@node1:/> /opt/cluster/solidDB/bin/solsql -x pwdfile:/etc/cluster/dbpass 'tcp localhost 2188' caa IBM solidDB SQL... [More]

How much memory or CPU will that CoD code activate anyway?

cggibbo 270000TMUJ | | Comments (11) | Visits (34956)

This little tip was passed on to me by a friendly IBM hardware engineer many years ago.   When entering a capacity on demand (CoD) code into a Power system, you can tell how many processors and how much memory will be activated, just by looking at the code you’ve given by IBM.   For example, the following codes, when entered for the appropriate Power system, will enable 4 processors (POD) and 64GB of memory (MOD). I can also tell* that once the VET code is entered, this system will be licensed for PowerVM Enterprise Edition (2C28).  ... [More]
