AIX 5.2 Workload Partitions for AIX 7 (5765-H38)
AIX 5.3 Workload Partitions for AIX 7 (5765-WP7)
New LPP offerings simplify migration of
AIX 5.2 or AIX 5.3 workloads to POWER7
– Run on top of AIX 7 and POWER7 processor-based server
Customer value
– Simplify consolidation of old workloads on new hardware
– Reclaim floor space and eliminate hardware support for obsolete servers
– Protects customer investment in application stacks
– Offering includes phone and fix support for AIX 5.2 or AIX 5.3 respectively
– Enables advanced capabilities such as SMT4, Live Application Mobility and Live Partition Mobility
– Provides a way for AIX 5.2 or AIX 5.3 clients to move up to POWER7
AIX levels supported are final service packs of final TLs: 5200-10-08 or 5300-12-04
SWMA provides limited support for AIX 5.2 or AIX 5.3 including phone support and limited new fix
support
– Fix support is limited to security, data integrity problems and critical issues and may not always be possible
WPAR restrictions apply:
– HACMP support only for the global instance
– NFS server not supported in a WPAR
– Device support is limited to devices directly supported in WPAR (and on POWER7)
– Because the performance commands and libraries are used from AIX 7, applications that are sensitive to output from these
commands may not work
SAN and virtual SCSI Devices are allowed inside an AIX 5.2 or AIX 5.3 WPAR

– New -C command argument to mkwpar to specify /tmp
alternative runtime environment Shared
/var
– Additional software (vwpar.images.base, or /home
vwpar.images.52/53) installed into 5.2/5.3 WPAR Private
System call compatibility logic (not layer) Runtime (AIX
– Some sys calls require VWPAR-specific logic Environment 5.2/5.3)
– Maps input, output parameters, and return codes
according to legacy semantic
/usr
– Transparent to appl. & wholly contained in kernel /opt
Access to Native OS Support
– Code is mounted from native runtime environment CRE Native OS Support
– Commands which must be at level of native runtime /nre/usr /nre/sbin /nre/opt
environment replace AIX files inside VWPAR.
– Includes configuration methods, ODM, LVM, FS, a few
libraries, and performance commands (native syscalls) 5.2/5.3 syscall compatibility
