Cluster Configuration Changed Help (SPA Inaccessible)
Overview
This dialog appears when a ServerNet PCI Adapter (SPA) in one of the nodes
in the cluster is no longer accessible by the cluster. The associated node
has been removed from active participation in the cluster. Refer to
What Happened to Inaccessible
SPA? to determine why the node is no longer accessible.
Responding to the Dialog
The dialog box has two buttons:
OK Button
Select OK to dismiss the dialog.
Help Button
Select Help to display this help text.
What Happened to Inaccessible
SPA?
The inaccessible SPA (node) may have been intentionally removed from the
cluster either temporarily or permanently with the Orderly Nodedown feature
(clusternode_shutdown(1M) command).
If the node was not removed intentionally, hardware or software
failure(s) have occurred. The list of suspect components includes:
-
SPA - It may have sustained one or more failures that affect both the X
and Y ports.
-
Cabling - The X and Y cables to the node may have been disconnected.
-
Multiple hardware failures - All nodes must be able to communicate with
all other nodes in the cluster. For example, if one node is unable to communicate
over its X path while a second node is unable to communicate over its Y
path, then the two nodes cannot communicate and one of them is removed
from the cluster. Multiple failures that disable both paths to a SPA cause
the node to be removed from the cluster. It is important to repair disabled
paths when they are first noted so cluster resources are not lost on subsequent
failures.
-
SPAD - A SPA driver error may have occurred.
Use the ServerNet States View to identify all disabled paths in the cluster.
Both paths to the affected node are disabled, but are there others? Refer
to Repairing
the Disabled Path in Disabled Paths Alert Help for troubleshooting guidelines
associated with disabled paths.
In addition to the ServerNet States View, the SPA driver (SPAD) messages
written to the system console and system log are useful for isolating the
failure(s). The NonStop Clusters for SCO UnixWare System Administrator's
Guide contains
troubleshooting information for each of the ServerNet SAN messages written
by the SPAD.
