Modify SAS Host

Overview

This function changes the SAS host information.

Caution

  • When no SAS hosts are registered, the [Modify SAS Host] function cannot be used.

  • When changing the SAS address or the host response of a SAS host that is currently being used, make sure to stop access to that SAS host. The server must be rebooted after the host response is changed.

Note

  • When the SAS host is registered in a host group, use the [Modify Host Group] function to change the host response. Refer to the [Modify Host Group (SAS)] function for details.
