Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

symcfg list -rdfg -metro

The -metro option replaces some information in the default display (shown in the previous section) with information specific to SRDF/Metro. These include:

Indication of whether the SRDF group was enabled for Witness or bias protection during the establish/restore.
Indication of whether Witness or bias protection is currently in effect.
SRDF groups that have Witness protection in effect, and the group is in the ActiveActive state, identify the witness array or virtual witness that they use.

NOTE:The symcfg list -metro command does not restrict group selection to Metro-related groups. It only selects the information that is output.

In the following example,

Group 115 on array 000197100084:
- Contains SRDF device pars that are configured for SRDF/Metro;
- Is configured to use Witness protection;
- Is currently Witness-protected; and
- The Witness array is 000197100087.
Group 116 on array 000197100084
- Contains SRDF device pairs that are configured for SRDF/Metro;
- Is configured to use Witness protection; but
- Is currently using bias.
Group 117 on Symmetrix 000197100084:
- Contains SRDF device pairs that are configured for SRDF/Metro;
- Is configured to use bias; and
- Is currently using bias.
Group 125 on Symmetrix 000197100084:
- Contains devices that are configured for SRDF/Metro;
- Is configured to use Array Witness protection; but
- Its Witness protection is degraded (only one side can see the witness array);
- The witness array is 000197100087
