ABSTRACT:
Maintaining SAN access rights during migration of operating systems including assigning, to a virtual SAN interface adapter of a source virtualization intermediary (SVI′) on the source server, at least two world wide port names (WWPN), identifying devices coupled for data communications to the SVI through the primary WWPN; selecting a target physical SAN interface adapter on a target server available to a target virtualization intermediary (‘TVI’) having a target virtual SAN interface adapter; assigning to the target virtual SAN interface adapter the secondary WWPN; identifying devices coupled for data communications to the TVI through the secondary WWPN; determining whether the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN; migrating the operating system from the source server to the target server if the devices coupled to the SVI through the primary WWPN are also coupled to TVI through the secondary WWPN.
