Changing the Mode on PowerVault 220S and
PowerVault 221S Enclosures
When toggling the bus configuration switch on a PowerVault 220S or
PowerVault 221S enclosure, the enclosure should be powered off. The bus
configuration switch is used to change the enclosure to split bus, joined bus,
or clustered mode. If you change the PowerVault 220S or PowerVault 221S
enclosure mode with the enclosure powered on, the enclosure may no longer
be displayed by Storage Management and you may notice other erratic
behaviors. In addition, the bus configuration switch on these enclosures is not
rated for frequent toggling.
