Issue Description
At an office, the S5000 disk arrays were connected to one IBM small machine, UltraPath-41.01.15T01.AIX6.1 software was installed in the AIX6.1 operating system. After LUN mappings were complete, LUNs were scanned in the AIX6.1 operating system and disks were queried. The LUNs mapped from the S5000 can be identified, but virtual disks were not generated.
