If a connection to the first management server fails, attempts
are made to connect to the subsequent management servers
in their order of specification..
DC2_HOST_LIST A list of the clustered nodes that reside in Data Center 2.
Multiple names can be defined by using commas as
separators.
QUERY_TIME_OUT(Default 120
seconds)
Sets the time in seconds to wait for a response from the
SMI-S CIMOM in storage management appliance. The
minimum recommended value is 20 seconds. If the value is
set to be smaller than 20 seconds, Metrocluster software
might time out before getting the response from SMI-S, and
the package fails to start with an error.
Package Attributes for Continentalcluster with EMC SRDF
This appendix lists all Serviceguard package attributes that have been modified or added for
Metrocluster with EMC SRDF. HP recommends that you use the default settings for most of these
variables, so exercise caution when modifying them:
AUTOR1RWSUSP Default: 0
This variable is used to indicate whether a package must be
automatically started when it fails over from an R1 host to another R1
host and the device group is in suspended state. If it sets to 0, the
package will halt unless ${PKGDIR}/FORCEFLAG file has been
created. The package halts because it is not known what has caused
this condition. This caused by an operational error or a Symmetrix
internal event, such as primary memory full. If in this situation you want
to automatically start the package, AUTOR1RWSUSP must be set to
1.
AUTOR1RWNL Default: 0
This variable indicates that when the package is being started on an
R1 host, the Symmetrix is in a Read/Write state, and the SRDF links
are down, the package automatically started. Although the script
cannot verify the state of the Symmetrix on the R2 side to validate
conditions, the Symmetrix on the R1 side is in a ‘normal’ state. To
require operator intervention before starting the package under these
conditions, set AUTOR1RWNL=1 and create the file
/etc/cmcluster/package_name/FORCEFLAG.
AUTOR1UIP Default: 1
This variable indicates that when the package is being started on an
R1 host and the Symmetrix is being synchronized from the Symmetrix
on the R2 side, the package will halt unless the operator creates the
$PKGDIR/FORCEFLAG file. The package halts because performance
degradation of the application will occur while the resynchronization
is in progress. More importantly, it is better to wait for the
resynchronization to finish to guarantee that the data are consistent
even in the case of a rolling disaster where a second failure occurs
before the first failure is recovered from. To always automatically start
the package even when resynchronization is in progress, set
AUTOR1UIP=0. Doing so will result in inconsistent data in case of a
rolling disaster.
AUTOR2WDNL Default: 1
AUTOR2WDNL=1 indicates that when the package is being started
on an R2 host, the Symmetrix is in a Write-disabled state, and the
SRDF links are down, the package will not be started. Since we cannot
verify the state of the Symmetrix on the R1 side to validate conditions,
