Coupling facility structure non-volatility and failure-isolation
from connectors is summarized by the following report:
text
Explanation
Where
text is:
An asterisk (*) before a structure name indicates a structure that does not satisfy a user request for
non-volatility and failure isolation from connectors. A connection name and/or the coupling facility
name(s) will also have an asterisk to indicate the unsatisfied condition(s).
An asterisk (*) or a dash (-) before a coupling facility name (CfName1 and/or CfName2) indicates a
structure instance allocated in a volatile coupling facility. A dash is used when non-volatility is
satisfied by the duplexed structure instance in the other coupling facility.
An asterisk (*) before a connection name indicates a connector that is not failure-isolated from the
structure instance(s). Iso1 and/or Iso2 will be "No" - indicating the connector's lack of
failure-isolation from CfName1 and/or CfName2 respectively.

This
is a report for CHECK(IBMXCF,XCF_CF_STR_NONVOLATILE). When
VERBOSE=NO is used when the check is run, only structures that
do not satisfy a user request for non-volatility andfailure-isolation
from connectors are listed.When VERBOSE=YES is used when the check
is run, all allocated structures are listed.
In
the report:
- Structure Name
- The name of a coupling facility structure.
- CfName1
- The name of a coupling facility in which an instance of the
structure is allocated.
- CfName2
- The name of a coupling facility in which an instance of the
duplexed structure is allocated. Blank when the structure
is not duplexed.
- Connection Name
- The name of a connection to the structure. Multiple connection
names might be listed for a single structure. Blank when no connections
exist - the structure is persistent.
- Req
- Connection specification for NonVolReq. Yes indicates
the user connected with NonVolReq=YES. No indicates the user connected
with NonVolReq=NO. N/A indicates the connection is failed-persistent
and has been reconciled into the CFRM active policy.
- Iso1
- Connection failure-isolation from CfName1. Yes indicates
the connector is failure-isolated from the coupling facilitiy identified
by CfName1. No indicates the connector is not failure-isolated from
the coupling facilitiy identified by CfName1. N/A indicates
the connection is failed-persistent.
- Iso2
- Connection failure-isolation from CfName2. Yes indicates
the connector is failure-isolated from the coupling facilitiy identified
by CfName2. No indicates the connector is not failure-isolated from
the coupling facilitiy identified by CfName2. N/A indicates
the connection is failed-persistent. Blank when the structure
is not duplexed.
