Description

This document attempts to explain the steps required to create the target (R2) EMC SRDF DeviceGroup on the remote server using "symdg create".

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".

 


Figure 1.0



Steps



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


Bashful # symdg list


No Symmetrix device groups were found



2.] To create the EMC DeviceGroup, type:


In this instance, the EMC DeviceGroup will be of a "RDF2" type, called "DopeyDg".


Bashful # symdg -type RDF2 create DopeyDg



3.] As illustrated above, EMC SYMDEV's 0072, 0073,0074 and 0075 will be assigned to DeviceGroup "DopeyDg".


Bashful # symld -sid 414 -g DopeyDg add dev 0072
Bashful # symld -sid 414 -g DopeyDg add dev 0073
Bashful # symld -sid 414 -g DopeyDg add dev 0074
Bashful # symld -sid 414 -g DopeyDg add dev 0075



4.] To validate the above changes, type:

Bashful # symdg list

                                                              Number of

  DopeyDg            RDF2     Yes    000290301414     4     0     0      0     0
 

 

Followed by:


Bashful # symrdf -g DopeyDg query


Device Group (DG) Name             : DopeyDg
DG's Type                          : RDF2
DG's Symmetrix ID                  : 000290301414    (Microcode Version: 5773)
Remote Symmetrix ID                : 000290300822    (Microcode Version: 5773)

 A(daptive Copy)    : D = Disk Mode, W = WP Mode, . = ACp off

 

5.] To rename the EMC LdevName references to match the EMC SYMDEV, type:


Bashful # symld -g DopeyDg rename DEV001 DEV072
Bashful # symld -g DopeyDg rename DEV002 DEV073
Bashful # symld -g DopeyDg rename DEV003 DEV074
Bashful # symld -g DopeyDg rename DEV004 DEV075




6.] To validate the LdevName changes, type:

Bashful # symrdf -g DopeyDg query
