6.3.3.2. Persistent Binding Consideration for Avoiding Rebooting of Host
AIX, HP-UX and Solaris hosts are configured for persistent bindings by Port ID method in HBA configuration file. Any
change in the 24-bit Port address invalidates the configuration file entry, prohibiting storage access. Since upgrading a switch
Core PID format changes the 24-bit Port ID area byte field as described above for all storage ports, the corresponding host
HBA configuration file persistent binding entries must be kept consistent with the Port ID. This is accomplished via one of the
following methods:
•
•
Matching the existing Persistent binding entry of the host to the modified Port ID.
Updating host configuration file.
