FABR-1024
Message
Probable
Cause
Indicates that the fabric size has exceeded the limit set by your value-line switches. Value-line switches
have a limited fabric size: a specified limit to the number of domains. This value is defined by your
specific value-line license key. The fabric size has exceeded this specified limit. The grace-period timer
has been initialized. If the grace period is complete and the size of the fabric is still outside the specified
limit, Web Tools is disabled.
Recommended
Action
Bring the fabric size within the licensed limits. Either a full fabric license must be added or the size of
the fabric must be changed to within the licensed limit. Contact your switch provider to obtain a full
fabric license.
Severity INFO
FABR-1029
Message
Probable
Cause
Indicates that a different flow control mode, as described in the message, is negotiated with the port at
the other end of the link. The flow control is a mechanism of throttling the transmitter port to avoid
buffer overrun at the receiving port. There are three types of flow control modes:
• VC_RDY mode: Virtual-channel flow control mode. This is a proprietary protocol.
• R_RDY mode: Receiver-ready flow control mode. This is the Fibre Channel standard protocol, that
uses R_RDY primitive for flow control.
• DUAL_CR mode: Dual-credit flow control mode. In both of the previous modes, the buffer credits
are fixed, based on the port configuration information. In this mode, the buffer credits are
negotiated as part of ELP exchange. This mode also uses the R_RDY primitive for flow control.
Recommended
Action
No action is required.
