Selectable boot settings, Enable LIP Reset, Login Retry Count

Enable LIP Reset

This setting determines the type of loop initialization process (LIP) reset that is used when the operating system initiates a bus reset routine. When this setting is Yes, the driver initiates a global LIP reset to clear the target device reservations. When this setting is No, the driver initiates a global LIP reset with full login. The default is No.

Enable LIP Full Login

This setting instructs the ISP chip to log in again to all ports after any LIP.

The default is Yes.

Enable Target Reset

This setting enables the drivers to issue a Target Reset command to all devices on the loop when a SCSI Bus Reset command is issued. The default is Yes.

Login Retry Count

This setting specifies the number of times the software tries to log in to a device. The default is 30 retries for Microsoft Windows Operating System environment. Please review the device driver README for the correct setting in other operating system environments.

Port Down Retry Count

This setting specifies the number of seconds that the software waits before it retries a command to a port returning port down status. The default is 30 seconds. In a DS4000 storage server configuration with the maximum number of drive expansion enclosures or in MCSC configurations, you should increase this setting to 70.

Link Down Timeout

This setting specifies the number of seconds the software that the software waits for a link down to come up. The default is 30 seconds.

Extended Error Logging
