Dynamic Reconfiguration
–
No parallel actions
Configuration measures which are performed in parallel to a DR process can prevent
the DR process from running successfully. The same applies for Solaris applications
which access the resources of an affected XSB in parallel to a DR process.
The following actions should not be performed during a DR process:
–
–

Failure to observe the recommendations given can lead to problems, e.g. to considerable

In the case of DR-disconnect no "extra" CPU may be connected in BS2000/VM2000.
No second DR process may be started – any attempt to do so is rejected. Only one
DR process can run on an SX server at any one time. DR processes are serialized
between the partitions of an SX server.
No PHP process (PCI Hot Plug) may be performed. Any attempt to initiate one with
the x2php command is rejected.
In PRIMEPOWER ServerView no BS2000 device may be configured on the XSB
concerned.
In BS2000 no ATTACH-DEVICE may be entered for a device on the XSB concerned.
In Solaris no PowerPath and no disk mirror may be configured on the XSB
concerned.
