Hi,
I have strange issue with the newly attached SAN storage disks. ioscan couldn't list the SAN disks. There is no errors/Clue on dmesg or syslog. Ran ioscan/insf -e and even rebooted the server. Disabled and enabled legacy mode.
#ioscan -fnC disk

Wondering why the paths are showing lunpathxx on powerpath o/p which is suppose to be cxtxdx.
Thanks & Regards,
