SCSI

Each row in this table describes a RAID controller module physical disk interface (an access path from the selected RAID controller module to the   physical disks). Each physical disk interface in the storage array that is associated with the RAID controller module appears in this table.

The SCSI physical disk interfaces table shows the following columns:

• The Channel column shows the  number of the physical disk interface.
• The Current ID column shows the  of the RAID controller module making the connection to a physical disk 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 displayed is either 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.

Fibre Channel

Each row in this table describes a RAID controller module physical disk interface, an access path from the RAID controller module to a single physical disk port on a storage array physical disk. There are two Fibre Channel physical disk interfaces to every physical disk, one to each physical disk port. Each physical disk interface in the storage system that is associated with the selected RAID controller module is displayed in this table.

The Fibre Channel physical disk interfaces table displays the following columns:

• The Channel column shows the  number of the physical disk interface.
• The Ports column shows the ports associated with each channel.
• The Connector Location column shows the connector locations for each channel.
• 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 displayed is either 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.

SCSI

Each row in this table describes a RAID controller module host interface (a connection from a selected SCSI RAID controller module to a ).

The SCSI host interfaces table shows the following columns:

• The Channel column shows the SCSI channel number of the RAID controller module host interface.
• The Current ID column shows the SCSI ID of the RAID controller module host interface.

Fibre Channel

Each row in this table describes a RAID controller module host interface (a connection from a Fibre Channel RAID controller module port to a port on a host). Each Fibre Channel RAID controller module can have one or more ports that can access ports on a host.

The Fibre Channel host interfaces table displays the following columns:

• The Channel column shows the RAID controller module ports used to connect to ports on a host.
• The Current ID column shows the current Fibre Channel loop ID of the RAID controller module port associated with the host interface. The loop ID is in the form decimal loop ID / hexadecimal .
• The Preferred ID column shows the preferred Fibre Channel loop ID of the RAID controller module port associated with the host interface. The Loop ID is in the form of a decimal loop ID / hexadecimal AL_PA. You can set the preferred ID through the Change Preferred Loop ID dialog. On some models of RAID controller module, you might have to set the preferred ID using a hardware switch on the RAID controller module.

Note: If the preferred ID of 126 indicating that the RAID controller module host interface uses a point-to-point connection rather than an , the value Not Applicable is displayed in this column.

• The NL-Port ID shows the hexadecimal NL-Port identifier of the RAID controller module port associated with this host interface. The NL-Port ID is a 24-bit address used in the S_ID and D_ID box 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 Rate Control column shows the current rate control based on the method used to set the data rate. The rate control displayed is either 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.
