The timeout parameter controls how many seconds the ESXi host must retry the I/O commands to a storage device in an all paths down (APD) state. You can change the default timeout value.
By default, the timeout parameter on your host is set to 140 seconds. You can increase the value of the timeout if, for example, storage devices connected to your ESXi host take longer than 140 seconds to recover from a connection loss.
- In the vSphere Client, navigate to the ESXi host.
- Click the Configure tab.
- Under System, click Advanced System Settings.
- In the Advanced System Settings table, select the Misc.APDTimeout parameter and click the Edit icon.
- Change the default value.
You can enter a value between 20 and 99999 seconds.
