APAR status

  • Closed as program error.

Error description

  • lspv is very slow in configurations where a large
    proportion
    of disks are not assigned to volume groups. Examples are
    IBM
    SDD and EMC powerPath configurations.
    

Local fix

Problem summary

  • There are a few places where lspv could work more optimally
    with the ODM in looking up disk information for lspv (no flags
    default) output.
    

Problem conclusion

  • Optimize things to reduce lspv runtime around 50% on systems
    with very many disks.
    

Temporary fix
