Managing WPARs
Listing WPARs lswpar * * * You can list summary data for system WPARs and application WPARs
Listing WPAR identifiers lparstat or uname * * You can list the identifiers for a WPAR using the lparstat command or the uname command.
Logging in to a WPAR clogin * * After you configure and activate a system WPAR that does not have a network connection, you can log in to it locally
Backing up WPARs savewpar, mkcd , or mkdvd * * * You can back up a WPAR
Restoring WPARs restwpar * * * You can restore a WPAR
Removing WPARs rmwpar * * * You can remove a WPAR
Stopping WPARs stopwpar * * * You can stop a WPAR from the global environment
Recovering incompatible detached WPARs syncwpar, inuwpar * * * It is possible that the system software in a detached workload partition (WPAR) might become incompatible with the levels of system software in the global environment. This occurs if software installation and maintenance tasks are performed independently in the global environment and the WPAR, or if a WPAR backup image from an incompatible system level was installed.
Managing software with detached WPARs syncwpar, inuwpar * * * System WPARs exist in two basic forms as either shared or detached (non-shared /usr) workload partitions, though the file system characteristics can vary.
Installing Apache in a WPAR rpm * Installing Apache allows you to take advantage of the portability and scalability of WPARs
Using the Advanced Accounting subsystem with WPARs
* You can use the Advanced Accounting subsystem to produce WPAR accounting reports
Using the trace facility with WPARs
mkwpar or chwpar -S privs+=PV_KER_RAS flag. * You can use the trace facility to isolate system problems by monitoring selected system events in a WPAR.  Enabled from Global Environment
Making software available to other WPARs
syncwpar or syncroot syncwpar only  syncroot only Software installed in the global environment, not always automatically available for use within your system WPAR
Modified and enhanced AIX commands for WPARs
various  see website   <<== * * Some commands have different or enhanced behavior in a WPAR environment.
Live Application Mobility  * * You can configure either WPAR type for mobility, which allows you to move running WPAR instances between physical systems using the AIX Workload Manager.

IBM PowerHA SystemMirror for AIX V6.1 and V7.1 adds Support for IBM AIX 5.2 Workload Partitions for AIX V7.1

Comments Off
by    in Cluster

January 21, 2011

IBM PowerHA SystemMirror for AIX* V6.1 and V7.1 for AIX V7.1 add support for IBM AIX 5.2 Workload Partitions for AIX V7 (Compatibility WPARs).

It is recommended to obtain the latest service updates for this support.

Please refer to the following information for support details. The specified levels, or later, are required for this support.

PowerHA SystemMirror
AIX
PowerHA V7.1, SP2PowerHA APAR IZ90890

PowerHA APAR IZ91056
AIX 7.1 TL0 SP2RSCT V3.1.0.0

AIX APAR IZ91004*
PowerHA V6.1, SP3
AIX V7.1 TL0 SP2RSCT V3.1.0.0

AIX APAR IZ91004*


The prerequisites for AIX 5.2 Workload partitions are as follows:

  • Versioned WPARs only support POWER7® hardware.
  • Versioned WPARs can be installed only on an AIX 7.1 operating system.
  • The latest available, and supported version of AIX 5.2 is technology level (TL) 10, and service pack (SP) 8. Therefore, any backup image that is used to create an AIX 5.2 WPAR must be from an AIX 5.2 system running the latest version.

Restrictions:

  • PowerHA 7.1 support for Versioned WPAR is restricted to 32 Service IP addresses (per WPAR-enabled Resource Group).
  • Mixed mode operation, where in some of the nodes of the WPAR-enabled resource group has Versioned WPAR software installed whereas some other nodes do not, shall not be supported by PowerHA.
  • Cloning (via the PowerHA corrective action) of WPAR profile, shall not be supported for Versioned WPARs (in PowerHA).


Notes:

  • APAR IZ91004 is included in RSCT V3.1.0.0 SP4
  • WPAR property changes do not take effect until the next time the resource group is brought on line

How to list WPAR state

Comments Off
by    in AIX

 Technote (FAQ)
 
Question
How can I list the state of my wpar(s) and display it's filesystem and process information from the global environment?
 
Answer
To list the state of all existing WPARs...
# lswpar
Name State Type Hostname Directory
---------------------------------------------
mywpar A S mywpar /wpars/mywpar



WPAR State Definitions
----------------------------------

Defined (D)
The workload partition has been defined by the mkwpar command and
is ready for use, but is not active. Start workload partitions in
this state with the startwpar command.
Loaded (L)
The workload partition has been configured in the kernel, but
processes have not yet been started. Note: This state is visible
only to programmatic consumers that use the lswpar command to
start a workload partition.
Active (A)
The workload partition is running normally.
Frozen (F)
A checkpoint operation is initiated, and the processes of the
workload partition are quiesced, awaiting the storing phase. Note:
The Frozen state is only visible when you use the lswpar command
to checkpoint a workload partition. The checkpoint or restart
function requires additional software package other than base
WPAR.
Paused (P)
A checkpoint or restart operation has been performed, and the
workload partition's processes are ready to be resumed or killed.
The checkpoint or restart functionality requires additional
software.
Transitional (T)
An administrative operation is in progress. The workload partition
is in the process of being created, started, stopped, configured,
and so on.
Broken (B)
An administrative operation failed, leaving this workload
partition in an unusable state.
