Field Description

○ Warning The disk is present but the system is having communication problems with the disk LED

processor. For disk and midplane types where this processor also controls power to the disk, power-

on failure will result in the Error status.

○ Error The disk is present but not detected by the expander.

○ Unknown Initial status when the disk is first detected or powered on.

○ Not Present The disk slot indicates that no disk is present.

○ Unrecoverable The disk is present but has unrecoverable errors.

○ Unavailable The disk is present but cannot communicate with the expander.

○ Unsupported The disk is present but is an unsupported type.

• For a power supply: Up, Warning, Error, Not Present, or Unknown.

• For a fan: Up, Error,, Off, or Missing.

• For a controller module or I/O module: Operational, Down, Not Installed, or Unknown.

• For a network port: N/A.

• For a host port:

○ Up – The port is cabled and has an I/O link.

○ Warning – Not all of the port PHYs are up.

○ Error – The port is reporting an error condition.

○ Not Present – The controller module is not installed or is down.

○ Disconnected – Either no I/O link is detected or the port is not cabled.

• For an expansion port: Up, Disconnectedor Unknown.

• For a CompactFlash card: Installed, Not Installed, or Unknown.

Systems Settings panel

The System Settings panel provides options for you to quickly and easily configure your system. Access the panel by doing one of the

following:

• In the Home topic, select Action > System Settings.

• In the System topic, select Action > System Settings.

• In the Welcome panel, select System Settings.

For more information on configuring system setting options, see Configuring system settings.

Resetting host ports

Making a configuration or cabling change on a host might cause the storage system to stop accepting I/O requests from that host. For

example, this problem can occur after moving host cables from one HBA to another on the host. To fix such a problem you might need to

reset controller host ports, or channels.

For FC, you can reset a single port. For an FC host port configured to use FC-AL, or loop topology, a reset issues a loop initialization

primitive (LIP).

For iSCSI, you can reset a port pair, either the first and second ports or the third and fourth ports.

For SAS, you can reset a port pair. Resetting a SAS host port issues a COMINT/COMRESET sequence and might reset other ports.

Rescanning disk channels

A rescan forces a rediscovery of disks and enclosures in the storage system. If both storage controllers are online and can communicate

with both expansion modules in each connected enclosure, a rescan also reassigns enclosure IDs to follow the enclosure cabling order of

controller A. For further cabling information, refer to your product's deployment guide.

You might need to rescan disk channels after system power-up to display enclosures in the proper order. The rescan temporarily pauses all

I/O processes, then resumes normal operation. It can take up to two minutes for enclosure IDs to be corrected.

You do not have to perform a manual rescan after inserting or removing non-FDE disks. The controllers automatically detect these

changes. When disks are inserted, they are detected after a short delay, which allows the disks to spin up.
