Chapter 3 121
This field contains a numeric value indicating the status change. If the
value is zero, then there has been no change to the node’s status. If the
value is +1, the node changed state from DOWN to UP. If the value is -1,
the node changed state from UP to DOWN.
HSTAT - Host link status change indicator
This field is an array of four values, one for each potential link associated
with NODE_NUM. Each entry indicates the status change of one link. If
the value is zero, then there has been no change to the link’s status. If
the value is +1, the link changed state from DOWN to UP. If the value is
-1, the link changed state from UP to DOWN.
ZCOM_SETYPE_RECONFIG - Dynamic Reconfiguration Event
The dynamic reconfiguration event is generated by using the zconfig
routine, typically after programmatically reconfiguring the ZCOM
subsystem during runtime operations. The event data is referenced
using sedata.recfg.<field name> and has the fields shown in Table 3-42.
CFG_CLASS - Type of reconfiguration performed
The field should contain the type of reconfiguration performed. Values
from 0 to 999 are reserved for use by the ZCOM subsystem. There is
currently one type defined, ZcCLASS_X25 (1), used to indicate that an
X.25 link has been reconfigured.
CFG_INFO1 - Caller supplied data
The application or driver calling zconfig to generate the dynamic
reconfiguration SEM should supply a class specific piece of data. In the
case where the CFG_CLASS is set to ZcCLASS_X25, this field will
contain the X.25 level 2 ZLU that was reconfigured.
