The local site name same as workload or sync target

In this scenario, the local site is the current workload site and the local site name is same as the workload site or the sync target site (as specified in the options file as a part of the SRDF/Star configuration).

Under these conditions, the online entry point checks the state of Star and then takes one of the following actions:

  • If STAR is in the PROTECTED state, the online entry point creates the lock file and the SRDFStar resource comes online.

  • If STAR is not in the PROTECTED state, the online entry point determines the state of the remote sites from the values of the syncSite and asyncSite attributes.

At this point, the remote sites can be in one of the following states:

  • HALTED

  • HALTFAIL

  • PATHFAIL

  • ISOLATED

  • CONNECTED

  • DISCONNECTED

The online entry point takes one of the following actions:

  • If one or both of the remote sites cannot transition to the PROTECTED state, the entry point checks the value of the ForceOnline attribute. If ForceOnline is set to 0, then the SRDFStar resource does not go online. If ForceOnline is set to 1, the entry point creates the lock file and the SRDFStar resource goes online.

  • If both of the syncSite and asyncSite attributes are specified and both the remote sites transition to the PROTECTED state, the entry point checks the value of OnlineOnState attribute.

    If OnlineOnState is set to protected, the entry point issues the command to move Star to the PROTECTED state in the background. The entry point then creates the lock file and the SRDFStar resource goes online.

    If OnlineOnState is set to star_protected, the entry point issues the command to move Star into the PROTECTED state in the foreground. That is, the SRDFStar resource goes online only after the command has finished. If the command is not successful, the entry point checks the value of the ForceOnline attribute. If ForceOnline is set to 0, the SRDFStar resource does not go online. If ForceOnline is set to 1, the entry point creates the lock file and the SRDFStar resource goes online.

  • If only one of the syncSite or asyncSite attributes is specified and that site transitions to the PROTECTED state successfully, the entry point creates the lock file and the SRDFStar resource goes online. Otherwise, the SRDFStar resource goes online only if ForceOnline is set to 1.

  • If neither of the syncSite nor asyncSite attributes is specified, the SRDFStar resource remains OFFLINE.
