Dr Runs In Bs2000 - Fujitsu Siemens Computers SX series User Manual

Performing DR

10.2.4 DR runs in BS2000

DR processes are always initiated and executed at Solaris level.
In BS2000/VM2000 no measures or actions are needed; the CPUs are automatically
disconnected or connected in accordance with the licenses.
The start and end and all BS2000 reconfiguration actions of a DR run are reported on the
console in BS2000 or VM2000.
The runs at BS2000/VM2000 level are described below on the basis of a CONSLOG listing
(of a VM2000 monitor system) which contains a DR-Connect:

In an MSCF network the DR process is covered by the following measures by MSCF to
ensure consistency

MSCF monitoring is placed in the locked status by the request for a lock by
the BS2000 DR component (here from VM1).
MSCF monitoring (in VM1) is placed in its original status by releasing the
lock.
BS2000 (from VM1) reports the start of the DR process.
VM2000 reports the start of the DR process.
the real CPU 4.
BS2000 (from VM1) reports the implicit automatic attachment (ATTACH) of
the virtual CPU 4.
VM2000 reports the end of the DR process.
BS2000 (from VM1) reports the end of the DR process.
