Find R2 pairs of a group of R1 devices

It is very easy to find the R2 pair of a single SRDF-R1 device.Just use the "symdev -sid 1234 show ABC"command shows the corresponding R2. But if you want to know the R2 pairs of a group of devices , then it will become a tedious task to show each device and pick the R2 device. I used to do this in a rather easy method and want to share with you.

1

We have below details

Array----------------> 1234
rdf group-----------> 100

Below are the R1 devices which we want to know the R2

123
234
567
89A
BCD

2

Make pair file

Make a pair file say pair.txt, with this devices and give any hexadecimal number as R2 pair device.( you may give the same device as pair device)

pair.txt
========

123   111
234   222
567   333
89A   444
BCD   555

3

Query pair file.

symrdf -sid 1234 -rdfg 100 -f pair.txt query

The output of this commands will show the actual R2 devices of the respective R1 devices.
