  • 1.  Cannot rescan new SAN storage without restart ESXi host

    Posted Sep 26, 2019 04:35 AM

    I deployed another SAN storage for 4 ESXi host，but cannot rescan it，I restart 1 ESXi host，it's can see the storage.

    I don't want to restart others,because it's some important system in it,so,how to scan to a new storage device without rebooting?

    UPDATE:The configuration of the switch and storage NO problem.

    Still confused...Can you see the problem with the screenshot?

    192.168.22.123 has been reboot，so it can see “20TB”

    192.168.22.124 did not perform reboot，just perform storage rescan and adapter rescan，cannot see “20TB”
