Description

This document attempts to explain the steps required to rename the LdevName references for an EMC SRDF "RDF group".

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".

 
In this instance, the LdevName references being renamed refer to the R1 devices.

Steps


1.] To list the current EMC "Device-Group" details, type:


Dopey # symrdf -g DopeyDg query


Device Group (DG) Name             : DopeyDg
DG's Type                          : RDF1
DG's Symmetrix ID                  : 000290300822    (Microcode Version: 5773)
Remote Symmetrix ID                : 000290301414    (Microcode Version: 5773)
RDF (RA) Group Number              :  11 (0A)


       Source (R1) View                 Target (R2) View     MODES
--------------------------------    ------------------------ ----- ------------
             ST                  LI      ST

DEV004  008F RW       0        0 NR 0075 WD       0        0 S..   Suspended

Total          -------- --------           -------- --------
  Track(s)            0        0                  0        0
  MB(s)             0.0      0.0                0.0      0.0

Legend for MODES:

 M(ode of Operation): A = Async, S = Sync, E = Semi-sync, C = Adaptive Copy
 D(omino)           : X = Enabled, . = Disabled
 A(daptive Copy)    : D = Disk Mode, W = WP Mode, . = ACp off
 

2.] To rename the current LdevName reference, use "symld" rename.


In this instance, the LdevNames for EMC DEV001,DEV002,DEV003 and DEV004 will be renamed to match the corresponding EMC SYMDEV reference.


Dopey # symld -g DopeyDg rename DEV001 DEV08C
Dopey # symld -g DopeyDg rename DEV002 DEV08D
Dopey # symld -g DopeyDg rename DEV003 DEV08E
Dopey # symld -g DopeyDg rename DEV004 DEV08F

 

3.] Validate LdevName changes.
