Hi Jeff,
>> Thanks Richard - that was my concern that the retention was a global parameter change, not one I could adjust for performance advisor only.
Change in retention period with 'dfm perf data modify' affects only performance advisor data, it has NO impact on Operations Manager (OM) reports, graphs related data.
However following reports available with OM web UI will have impact as these reports are specific to performance advisor.
storage-system-performance-summary performance summary of storage system
storage-system-NAS-performance-summary NAS performance summary of storage system
storage-system-SAN-performance-summary SAN performance summary of storage systems
aggregates-performance-summary performance summary of aggregate
volumes-performance-summary performance summary of volume
volumes-NAS-performance-summary NAS performance summary of volume
volumes-SAN-performance-summary SAN performance summary of volume
qtrees-performance-summary performance summary of Qtree
luns-performance-summary performance summary of LUN
disks-performance-summary performance summary of Disks
vfiler-performance-summary performance summary of vFilers
Please let me know if I can provide more details on this.
