AIX Info
Summary: ALthough AIX is by now on version 7.3 I find these old pages so fascinating I decided to keep them. On this page I'll show you how to retrieve information about the AIX installation and the hardware it's installed on. This page is for AIX 5.3 and 6.1.
Date: Between 2010-2013
Refactor: 21 December 2024: Checked formatting. Translated some stuff from Dutch to English.

CPU
{sys034_partition3} / # lsattr -El proc0

smt_enabled true Processor SMT enabled False
smt_threads 2 Processor SMT threads False
state enable Processor state False
type PowerPC_POWER6 Processor type False
Inside a partition you can see the processor settings with the lparstat command:
# lparstat System configuration: type=Dedicated mode=Capped smt=On lcpu=2 mem=3072 %user %sys %wait %idle ----- ---- ----- ----- 0.0 0.1 0.0 99.9
Here you can see that the processors are dedicated, in capped mode, simultaneous multi threading is on and there are two logical processors. You can check this with the bindprocessor command:
# bindprocessor -q The available processors are: 0 1
Simultaneous multi threading kun je bekijken en aan of uitzetten met het smtctl commando:
# smtctl
This system is SMT capable.
SMT is currently enabled.
SMT boot mode is not set.
SMT threads are bound to the same physical processor.
proc0 has 2 SMT threads.
Bind processor 0 is bound with proc0
Bind processor 1 is bound with proc0
# smtctl -m off
smtctl: SMT is now disabled. It will persist across reboots if
you run the bosboot command before the next reboot.
# bindprocessor -q
The available processors are: 0
# smtctl -m on
smtctl: SMT is now enabled. It will persist across reboots if
you run the bosboot command before the next reboot.
You can extend the lparstat command to see the entitlement for example:
# lparstat -i Node Name : lpar1 Partition Name : aix53 Partition Number : 2 Type : Dedicated-SMT Mode : Capped Entitled Capacity : 1.00 Partition Group-ID : 32770 Shared Pool ID : - Online Virtual CPUs : 1 Maximum Virtual CPUs : 4 Minimum Virtual CPUs : 1 Online Memory : 3072 MB Maximum Memory : 4096 MB Minimum Memory : 128 MB Variable Capacity Weight : - Minimum Capacity : 1.00 Maximum Capacity : 4.00 Capacity Increment : 1.00 Maximum Physical CPUs in system : 4 Active Physical CPUs in system : 4 Active CPUs in Pool : - Unallocated Capacity : - Physical CPU Percentage : 100.00% Unallocated Weight : -
Check CPU 32/64 bits
Give this command to check if you're on a 32 or a 64 bits system.

You can see the network cards with the lsdev command:
# lsdev -Cc adapter ent0 Available Logical Host Ethernet Port (lp-hea) ent1 Available Logical Host Ethernet Port (lp-hea) lhea0 Available Logical Host Ethernet Adapter (l-hea) vsa0 Available LPAR Virtual Serial Adapter vscsi0 Available Virtual SCSI Client Adapter
As you can see here you have a logical host ethernet adapter with two ports. These ports each have an interface:
# lsdev | grep ^e en0 Available Standard Ethernet Network Interface en1 Defined Standard Ethernet Network Interface ent0 Available Logical Host Ethernet Port (lp-hea) ent1 Available Logical Host Ethernet Port (lp-hea) et0 Defined IEEE 802.3 Ethernet Network Interface et1 Defined IEEE 802.3 Ethernet Network Interface
The en0 and en1 devices are the interfaces where you can configure the IP configuration on:
# ifconfig en0
en0: flags=1e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
inet 10.1.3.7 netmask 0xffff0000 broadcast 10.1.255.255
tcp_sendspace 131072 tcp_recvspace 65536
Using lscfg you can see the physical port you are using:
# lscfg -l ent* ent1 U78A5.001.WIH091C-P1-T7 Logical Host Ethernet Port (lp-hea) ent0 U78A5.001.WIH091C-P1-T6 Logical Host Ethernet Port (lp-hea)
As you can see the ports are on the same card but have a different location code. The T6 and T7 are the physical ports on the same card.
Note: A IVE/HEA card with two ports has 1 group in which both ports are stopped to hang partitions on. This group has 16 logical ports which means you can hang 16 partitions on it. This can be changed by changing the MCS (multi core scaling) value. With a value of 1 you have 16 logical ports, with a value of 2 you have 8 logical ports and so on.
The logical ports can be viewed using the lsslot command:
# lsslot -c port LHEA Port Name Description Device(s) Port 3 Logical HEA Port ent0 Port 5 Logical HEA Port ent1
You have port 3 and 5 in use here.
