A virtual Ethernet adapter is to be added to the LPAR aix01 with IBM PowerVM. The data in detail:
HMC: hmc01
managed system: ms25
LPAR: aix01
profile: standard
virtual slot number: 4
Port-VLAN-ID: 900
virtual Ethernet switch: ETHERNET0(default)
additional VLANs: none
The command on the associated HMC hmc01 is:
hscroot@hmc01:~> chhwres -m ms25 -r virtualio --rsubtype eth -o a -p aix01 -s 2 -a 'ieee_virtual_eth=0,port_vlan_id=900'
hscroot@hmc01:~>
If the currently used profile of the LPAR is not automatically synchronized, then the additional virtual Ethernet adapter should also be added to the profile:
The following SEA on a virtual I/O server is no longer required:
$ lsdev -dev ent48
name status description
ent48 Available Shared Ethernet Adapter
$
Attempting to delete the SEA using rmvdev fails with the following error message:
$ rmvdev -sea ent48
Some error messages may contain invalid information
for the Virtual I/O Server environment.
Method error (/usr/lib/methods/ucfgcommo):
0514-062 Cannot perform the requested function because the
specified device is busy.
$
The SEA is still in use. One possibility is the use of LLDP. This can be checked with the lsdev command:
$ lsdev -dev ent48 -attr lldpsvc
value
yes
$
In this case LLDP is active on the SEA and must first be stopped before the SEA can be deleted. Stopping LLDP on the SEA can be easily done by changing the lldpsvc attribute to the value “no“:
This post shows how to download AIX installation ISO images from the IBM Entitled Systems Support website. A valid IBMid and a current IBM software maintenance agreement (SWMA) are required for the download.As an example we show the download of the AIX installation ISO images for AIX 7.2 TL5.However, ISO images for other AIX versions or other software, e.g. PowerHA, can also be downloaded in the same way.
AIX and other software can be downloaded from the IBM Entitled Systems Support website. The URL for the website is:
In order to log in, you need a valid IBMid and a valid software maintenance contract. After clicking on the blue “Log in” button, a login mask appears.
After entering a valid IBMid and confirming with the “Continue” button, you will be asked for a password.
After entering the password, the main page of Entitled Systems Support appears.
“My Entitled Software” should be selected to download software.
From the displayed selection of options, the “Software Downloads” link should be clicked.
The software to be downloaded can be selected either by specifying the category, or the machine type, or by directly selecting a product. We show the variant “By category”, by selecting the category “AIX” and the desired version “V7R2 (GA)” for AIX 7.2.
From the list of available “AIX 7.2” products, “AIX 7.2 TL support” should be selected.
From the list of available packages, the package for the desired TL (AIX 7.2 TL05) should be selected. Pressing the “Continue” button confirms the selection.
Before the software can finally be downloaded, IBM’s general terms and conditions must be confirmed.
Next you have to select whether the download should be done via the browser or with the help of the download director. We have decided to download using a browser.
Next, the available images are displayed. We select the install images “AIX v7.2 Install DVD 1”, “AIX v7.2 Install DVD 2” and “AIX v7.2 Install flash”.
The progress of the download can be followed via the browser:
PowerHA, PowerVM or any other software can be downloaded in the same way via IBM Entitled Systems Support (ESS). However, a valid software maintenance contract for the corresponding software is always required.
During a TSM operation, the following error message occurs:

A possible cause is the missing certificate of the associated TSM instance, in the above case TSM01. The missing certificate can be found on the TSM server in the directory of the instance. The instance directory is usually given to the TSM server process (dsmserv) when it is started with the “-i” option:
The certificate cert256.arm should then be copied to the client system, we assume it has been copied to /tmp.
The dsmcert command for managing certificates is located under /usr/tivoli/tsm/client/ba/bin64. The certificate can then be installed (added) with the following call:
# cd /usr/tivoli/tsm/client/ba/bin64
# ./dsmcert -add -server TSM01 -file /tmp/cert256.arm

In the simplest case, a SEA (Shared Ethernet Adapter) can consist of just one trunking adapter. A SEA can have up to 16 trunking adapters, whereby each of the trunking adapters can have up to 20 additional VLANs in addition to the port VLAN ID.
The group mygroup currently has no members (users=””).
To add the two local users user01 and user02 to the group mygroup, the “-m” (member) option must be used. Then follows a plus sign “+” for add and a comma-separated list of user names. The last argument is the group:
The output of lsgroup shows that the user06 is also a member of the group mygroup. However, membership cannot be revoked in this case:
# chgrpmem -m - user06 mygroup
Cannot drop "user06" from primary group "mygroup".
#
A user must always have a primary group! The chgrpmem command can only be used to manage users’ additional memberships. The primary group can only be changed with the chuser command.
Note: The chgrpmem command and the “-a” option can also be used to change the administrators of a group. However, this is rarely used in practice and is therefore not addressed here.
