Description

This document attempts to explain the steps required to refresh the VxVM (Veritas Volume Manager) hardware awareness content for EMC SRDF related luns.

In this instance the configuration consists of "4" EMC SRDF "R1" devices presented to production server "Dopey" from EMC Symmetrix id (SID) "822".
An additional "4" EMC SRDF "R2" devices have been presented to DR server "Bashful" from EMC Symmetrix ID (SID) "414".


Note: As of 5.0 MP3 onwards, the VxVM CLI command "vxdisk -e list" is capable of reporting the extended attribute based content for EMC BCV, BCV-NR, MIRROR, SRDF-R1, SRDF-R2, TDEV device states and EMC lun types.


Figure 1.0





Steps:


1.] Ensure the SRDF pairing has been completed for the R1 and corresponding R2 devices.


In this instance, the EMC SRDF "DeviceGroup" is named "DopeyDg".
