The relationships attribute of the HACMPsvcpprc HACMP ODM class can store character strings of a total length of 1024 chars

Current PowerHA configuration contains following limitations. The most important limitation is 1024 chars for SVC Metro Mirror relationships. This limitation is not set on number of Metro Mirror relations, but on number of chars. In client's big environments 1024 chars for Metro Mirror relation names is not enough.

# odmshow HACMPsvcpprc
class HACMPsvcpprc {
char svcpprc_consistencygrp[129]; /* offset: 0xc ( 12) */
char MasterCluster[129]; /* offset: 0x8d ( 141) */
char AuxiliaryCluster[129]; /* offset: 0x10e ( 270) */
char relationships[1024]; /* offset: 0x18f ( 399) */
char CopyType[16]; /* offset: 0x58f ( 1423) */
char RecoveryAction[16]; /* offset: 0x59f ( 1439) */
