NETAPP - How to remove the unmapped LUNs from HPUX?
Hi, Storage team has mapped some LUNS to HPUX box and was visible. They have then unmapped the LUNs and assigned another set of LUNs. Now I can see unmapped LUNs are showing NO_HW in ioscan output.
We have used rmsf -H [hardware_path] command to remove those entries from ioscan. Now it is not visible in ioscan output. But the 'sanlun lun show -p' command shows older LUNs also. How to remove them?

As shown above, two paths are visible now and two paths are unmapped. How to remove the unmapped paths?
