Fix A SAN Datastore Inaccessible On A ESXi Host

A SAN datastore is shown inaccessible on one of the ESXi hosts in the cluster. Other ESXi hosts can access that datastore without problem.

Solution: restart the ESXi management agents on the ESXi host

There are a few ways to restart the management agents (KB1003490).

• From the Direct Console User Interface (DCUI)
• Press F2 to customize the system
• Log in as root
• Under Troubleshooting Options, select Restart Management Agents
• From the Local Console (Alt + F2) or SSH
• Log in as root
• run these commands
• /etc/init.d/hostd restart
• /etc/init.d/vpxa restart
• if the hostd is not restart, use KB1005566 to find and kill hostd Process ID (PID), then start it again (/etc/init.d/hostd start)
• alternatively
• To reset the management network on a specific VMkernel interface, by default vmk0
• esxcli network ip interface set -e false -i vmk0; esxcli network ip interface set -e true -i vmk0
• Note: run the above commands together, using a semicolon (;) between the two commands
• To restart all management agents on the host
• services.sh restart
• Caution:
• check if LACP is enabled on the VDS’s Uplink Port Group
• If LACP is not configured, the services.sh script can be safely executed
• If LACP is enabled and configured, do not restart management services using services.sh. Instead restart independent services using /etc/init.d/hostd restart and /etc/init.d/vpxa restart.
• If the issue is not resolved, take a downtime before restarting all services with services.sh
