In situations below, the disk devices will require re-configuration: 1. Converting SRDF from/to Non-SRDF device 2. Due to host failure or planned maintenance, RDF1 (R1) and RDF2 (R2) are swapped 3. Symmetrix FA ports attached to the host have sc3/sc2 bit set Before performing above change, proceed with following procedure: 1). Stop All running EMC Agents including EMC ControlCenter, Symmetrix, Storage Device Management Agents. 2). Stop all Applications use Symmetrix devices 3). Unmount the filesystems: # umount <Filesystem> 4). Vary off the volumegroups # varyoffvg <VGname> 5). Skipp step5 to step7 if no powerpath installed. If PowerPath is installed, you need to de-configure PowerPath: #powermt remove hba=all dev=all 6). Deconfigure the fscsi driver and hdisks: # rmdev -Rdl fscsi<n> 7). Switch off the Fibre Adapter: # rmdev -dRl fcs<n> After complete the RDF swap or changes listed above proceed with below procedure: 1).
