Migration considerations
LoadLeveler 2.2 supports node by node migration from LoadLeveler 2.1 (if a PTF
is applied to 2.1). LoadLeveler provides other mechanisms for migration from
LoadLeveler 1.3 to 2.1, including the use of separate LoadLeveler clusters.
Migration limitations:
1. If LoadLeveler and PE are used with PSSP 3.2, the migration to PSSP 3.2,
LoadLeveler 2.2 and PE 3.1 must be completed simultaneously.
2. LoadLeveler 1.3.0 with PSSP 2.4 and AIX 4.3.2 can be migrated to
LoadLeveler 2.1 without changing PSSP and AIX levels.
3. LoadLeveler 2.1 permits the migration of PSSP 2.4 or 3.1 and AIX 4.3.2 to
PSSP 3.2.
Coexistence
LoadLeveler 2.2 can coexist with LoadLeveler 2.1 within a cluster (PTF on 2.1 is
required for this). LoadLeveler 2.2 does coexist with PSSP 3.1.1 and 3.2 and AIX
4.3.3. LoadLeveler 1.3.0 coexists with PSSP 2.2, 2.3 and 2.4 and the
corresponding levels of AIX. LoadLeveler 2.1 coexists with PSSP 2.4 and 3.1
and AIX 4.3.3. LoadLeveler 2.1 coexists with PSSP-3.2 and AIX 4.3.3, without
PE.
Coexistence of LoadLeveler with Parallel Environment: When LoadLeveler and
Parallel Environment exist on the same node, they must be at one of the
following combinations:
򐂰
LoadLeveler 2.2 with Parallel Environment 3.1
򐂰 LoadLeveler 2.2 with Parallel Environment 2.4
򐂰 LoadLeveler 2.1 with Parallel Environment 2.4
򐂰 LoadLeveler 1.3 with Parallel Environment 2.3
򐂰 LoadLeveler 1.3 with Parallel Environment 2.2
