Resetting a host port

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 (channels).
For a Fibre Channel host port configured to use FC-AL (loop) topology, a reset issues a loop initialization
primitive (LIP). For iSCSI, resetting a port might reset other ports. For SAS, resetting a host port issues a
COMINIT/COMRESET sequence and might reset other ports.
To reset a host port
1. In the Configuration View panel, right-click the system and select Tools > Reset Host Port.
2. Select the port to reset. For example, to reset controller A port 1, select A1.
3. Click Reset Host Port.

Rescanning disk channels

A rescan forces a rediscovery of disks and enclosures in the storage system. If two Storage Controllers are
online, rescan also reassigns the enclosure IDs of attached enclosures based on controller A's enclosure
cabling order. A manual rescan may be needed after system power-up to display enclosures in the proper
order. A manual rescan temporarily pauses all I/O processes, then resumes normal operation. It can take
up to two minutes for the enclosure IDs to be corrected.
A manual rescan is not needed after inserting or removing 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.
To rescan disk channels
1. Verify that both controllers are operating normally.
2. In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.
3. Click Rescan.

Restoring system defaults

If the system is not working properly and you cannot determine why, you can restore its default
configuration settings. You then can reconfigure the settings that are necessary to use the system.
To restore defaults, use the CLI's restore defaults command, as described in the CLI reference guide.
