Viewing the Controller Properties

Use the Controller Properties option to view the properties of a selected .


Note:

You also can view controller properties in the when you want to view properties on all controllers simultaneously.

The Base tab shows the current configuration information for the selected controller, such as the manufacturer and the serial number of the controller, cache size, processor size, date, and time. The version of storage management software and the model of controller determine what appears in the Pending configuration text boxes. This information is “Not Applicable” or populated with information about the , packages, or both waiting to be activated.

The Host Interfaces tab shows information for the host interfaces attached to the storage subsystem. The information on the Host Interfaces tab varies depending on the interface type.

Host Disk Drive Interface Information

Interface

Information Shown

SCSI

Each row in this table describes a controller host interface. A controller host interface is a connection from a selected SCSI controller to a .

The SCSI Host Interfaces table shows these columns:

  • The Channel column lists the SCSI channel number of the controller host interface.
  • The Current ID column lists the SCSI ID of the controller host interface.

Fibre Channel

Each row in this table describes a controller host interface. A controller host interface is a connection from a Fibre Channel controller port to a port on a host. Each Fibre Channel controller might have one or more ports that can access ports on a host.

The Fibre Channel Host Interfaces table shows these columns:

  • The Channel column lists the controller ports used to connect to ports on a host.
  • The Current ID column lists the current Fibre Channel loop ID of the controller port that is associated with the host interface. The loop ID is in the form decimal loop ID/hexadecimal .


    Note:

    If the preferred ID is set to 126, the value indicates that the controller host interface is using a point-to-point connection rather than an . Therefore, Not Applicable appears in this column.

  • The Preferred ID column lists the preferred Fibre Channel loop ID of the controller port that is associated with the host interface. The Loop ID is in the form decimal loop ID/hexadecimal AL_PA. You can set the preferred ID using the Change Preferred Loop ID option. On some models of controllers, you might have to set the preferred ID by using a hardware switch on the controller.
  • The NL_Port ID column lists the hexadecimal NL_Port identifier of the controller port that is associated with this host interface. The NL_Port ID is a 24-bit address that is used in the S_ID field and the D_ID field of a frame.
  • The Max Rate column shows the maximum data transfer rate of the Fibre Channel interface.
  • The Current Rate column shows the current data transfer rate of the Fibre Channel interface.
  • The Link Status column shows the current status for the link and indicates whether the link is currently up or down.

The Disk Drive Interfaces tab shows information for the disk drive channel interfaces that are attached to the storage subsystem. The information in the Disk Drive Interfaces tab varies, depending on the interface type.

Controller-Disk Drive Interface Information

Interface

Information Shown

SCSI

Each row in this table describes a controller-disk drive interface. A controller-disk drive interface is an access path from the selected controller to the disk drives. This table shows every disk drive interface in the storage subsystem that is associated with the controller.

The SCSI Disk Drive Interfaces table shows these columns:

  • The Channel column lists the number of the disk drive interface.
  • The Current ID column lists the of the controller making the connection to a disk drive through this channel.
  • The Max Rate column shows the maximum data transfer rate of the SCSI interface.
  • The Current Rate column shows the current data transfer rate of the SCSI interface.
  • The Rate Control column shows the current rate control based on the method used to set the data rate. The rate control shown is Fixed, Auto, Switch, or Unknown.
  • The Link Status column shows the current status for the link and indicates whether the link is currently up or down.

Each row in this table describes a controller-disk drive interface. A controller-disk drive interface is an access path from the controller to a single disk drive port on a storage subsystem disk drive. There are two Fibre Channel disk drive interfaces to every disk drive, one to each disk drive port. This table shows every disk drive interface in the storage subsystem that is associated with the selected controller.

The Fibre Channel Disk Drive Interfaces table shows these columns:

  • The Channel column lists the channel number of the disk drive interface. Multiple channels can be used on a single controller.
  • The Current ID column lists the actual loop ID of the controller port connecting through this channel to a disk drive port.
  • The Max Rate column shows the maximum data transfer rate of the Fibre Channel interface.
  • The Current Rate column shows the current data transfer rate of the Fibre Channel interface.
  • The Rate Control column shows the current rate control based on the method used to set the data rate. The rate control shown is Fixed, Auto, Switch, or Unknown.
  • The Link Status column shows the current status for the link and indicates whether the link is currently up or down.

The Network tab shows these controller network parameters:

  1. In the Physical pane, select a controller, and select Controller >> Properties .
  2. Click Close.
