I think that these infrastructure change not affect the HW paths, however if you can say more data
- HBA model
- Drivers used (HBA native or San Foundation drivers)
- method of disk administration (SVM, VXVM)
- Cluster installed (Sun Cluster, VCS)
basically, if youy disks are the strcuture
c4t50600e0000000007ed0
the target component is based in the WWN of Array Port, and device component is based in LUN number assigned in the array.
The Switch change not affect this components
NOTE: if your new switch have 8Gbps ports and your HBA are to 2/4 Gbps I suggest read the brocade recommendation about of "fillword modes"

hba_refreshinformation
HBA_RefreshInformation(3HBAAPI) Common Fibre Channel HBA Information Library Functions HBA_RefreshInformation(3HBAAPI)
NAME
HBA_RefreshInformation, HBA_RefreshAdapterConfiguration - refresh information for a specific HBA
SYNOPSIS
cc [ flag... ] file... -lHBAAPI [ library... ]
#include <hbaapi.h>
void HBA_RefreshInformation(HBA_HANDLE handle);
void HBA_RefreshAdapterConfiguration(void);
PARAMETERS
handle an open handle returned from HBA_OpenAdapter(3HBAAPI)
DESCRIPTION
The HBA_RefreshInformation() function requests that the underlying VSL reload all information about the given HBA. This function should be
called whenever any function returns HBA_STATUS_ERROR_STALE_DATA, or if an index that was previously valid returns HBA_STATUS_ERROR_ILLE-
GAL_INDEX. Because the underlying VSL can reset all indexes relating to the HBA, all old index values must be discarded by the caller.
The HBA_RefreshAdapterConfiguration() function updates information about the HBAs present on the system. This function does not change any
of the relationships between the HBA API and adapters that have not been reconfigured. HBA handles continue to refer to the same HBA even
if it is no longer installed. The HBA name or index assigned by the library remains assigned to the same HBA even if it has been removed
and reinstalled, as long as the bus position, WWN, and OS device have not changed. Adapter that have been removed and not replaced cannot
have their HBA handles, HBA names, and HBA indexes reassigned. Calls to these adapters will generate HBA_STATUS_ERROR_UNAVAILABLE.
