Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

When write pacing is active at both group-level and device-level, Enginuity monitors both the SRDF link performance of the SRDF/A session and the performance of the devices on the R2 side.

Restrictions

• The symrdf activate/deactivate -rdfa_pace commands act on all devices in the SRDF group.
• The R1 array is accessible.
• The SRDF/A session under control is active and contains at least one participating device.
• The symrdf deactivate -rdfa_pace command requires the following:
  • The R2 array is accessible to verify that there are no TimeFinder/Snap or TimeFinder/Clone sessions using the R2 devices before deactivating device-level pacing.
  • If the SRDF/A session is in the transmit idle state, issue symrdf deactivate -rdfa_pace -symforce from the R1 side.

Examples

To activate group-level and device-level write pacing simultaneously for the ConsisGrp Consistency Group:

symrdf -cg ConsisGrp activate -rdfa_pace

To deactivate both group-level and device-level write pacing on the devices in DeviceFile2:

symrdf -file DeviceFile2 -sid 55 -rdfg 2 deactivate -rdfa_pace
