"Cloud Ready" AIX Images
PowerVC compatible "ready to deploy" images for AIX 7.1 TL 5 and AIX 7.2 TL 2 “In addition to installation images for AIX, "cloud" image formats are also made available that can be readily deployed with PowerVC. These images contain a default AIX base media install configuration that includes Cloud Init and its dependencies. The images can be obtained from the IBM Entitled System Support website or IBM Passport Advantage. For AIX 7.1 TL 5 SP0 and AIX 7.2 TL 2 SP0, the image files have the following names”.... [More]

AIX 7.1 – DSM dgetmacs.
I received an email this week from a
colleague that worked with me on the NIM
Redbook back in 2006. He was experiencing an issue with DSM and NIM. He was
attempting to use the dgetmacs command to obtain the MAC address of the network adapters on an LPAR. The
command was failing to return the right information. This was the output from his attempt
with dgetmacs : # dgetmacs -n lpar1 Using an adapter type of "ent". Could not dsh to node lpar1. Attempting to use openfirmware method to
collect MAC addresses. Acquiring adapter... [More]

Checking your queue depth with kdb.
Just say you
change the queue_depth on a hdisk
with chdev –P . This updates the devices
ODM information only, not its running configuration. The new value will take
effect next time I reboot the system. So now I have a different queue_depth in the ODM compared to the
devices current running config (in the kernel). What if I
forget that I’ve made this change to the ODM and forget to reboot the system
for many months? Someone complains of an I/O performance issue....I check the
queue_depths and find they appear to be set appropriately... [More]

Cluster Aware AIX
Using Cluster Aware AIX with AIX 7.1 you can create a cluster of AIX
nodes. This interconnected cluster of nodes can immediately provide several
capabilities, such as: ·
Clusterwide event management. ·
Communication and storage events: o
Node UP and node DOWN o
Network adapter UP and DOWN o
Network address change o
Point-of-contact UP and DOWN o
Disk UP and DOWN o
Predefined and user-defined events ·
Clusterwide storage naming service ·
Clusterwide command... [More]

Creating a CAA cluster on AIX 7.1.
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]... [More]

NIM Master, NIMSH and SSL on AIX 7.1 TL4 SP3
Whilst working with one of my AIX customers recently I discovered a problem with NIMSH and SSL. The customer had updated their NIM master from AIX 7.1 TL4 SP1 to AIX 7.1 TL4 SP3 . After the SP update, any attempt to connect to a NIM client (over NIMSH+SSL), from the NIM master, would simply hang. For example, we tried to list the filesets on the NIM client with this command, which never returned any output. [root@750lpar4]/ # nim -o lslpp 750lpar9 The /var/adm/ras/nimsh.log file, on the NIM client, showed that the NIMSH session... [More]

nimadm - multibos error!?
I’ve been working with a customer recently on
an issue with nimadm . They were
attempting to migrate a system from AIX 5.3 to 7.1 using nimadm . The NIM client AIX
level was 5.3 TL12 SP4 and the NIM master was running AIX 7.1 TL1 SP1. lpar1

Renaming devices in AIX 7.1
I remember reading this interesting document about some challenges
renaming AIX devices. http://gibsonnet.net/aix/ibm/The_Fun_of_Oracle_RAC_ASM_and_Device_Names.doc This poor guy had to jump through some hoops to rename some disk
and network devices in a clustered AIX (Oracle RAC) environment. This comment stayed with me: “ The easy way to get network
adapters and disk names to match between systems would be to run
something like # chdev –l old_name –n new_name Except, this command option does NOT exist. ” Since then I’ve... [More]

Updating your NIM master to AIX 7.1 TL2? Take note!
After
updating my NIM master to AIX 7.1 TL2 SP1 (7100-02-01-1245), I noticed a
problem. Whenever I installed a new AIX partition using NIM, the resources
allocated to the NIM client were not being de-allocated, even though the installation was completing successfully. Also,
if I tried to run my usual ‘NIM client reset’ script (below), the resources
were still allocated. #!/usr/bin/ksh # Reset a
NIM client. if [[
"$1" = "" ]] ; then echo Please specify a NIM client to reset
e.g. aixlpar1. else if lsnim -l $1... [More]
