We have a situation on a server (RAC nodes) with lot of ASM Disks that are going to rezone to more FA ports down all 4 HBAs so the OS now would have scan more PATHS. Already it takes about 45 minutes to reboot each time. Now after this i suspect it is going to take even more. Any thoughts on speeding this up ?</P><P>&nbsp;</P><P>Simon G</P> Wed, 01 Feb 2012 22:26:35 GMT Simon_G 2012-02-01T22:26:35Z https://community.hpe.com/t5/operating-system-linux/rhel5-prevent-rescaning-every-single-san-device/m-p/5516521#M53520 <P>Greetings!</P><P>&nbsp;</P><P>Is there a way possible to prevent this scenario in scsi_mid_layer?
