SAS Storage System
Select a storage system item from the SAS HBA submenu to display the following information about
storage systems.
• Connection Type displays the type of drive enclosure or box. The following types of enclosures
are possible:
◦ SCSI Attached—This storage system is attached to the server through SCSI cable.
◦ SAS Attached—This storage system is attached to the server with a SAS cable.
◦ Unknown— The Storage Agents are unable to determine the type of connection.
• Vendor displays the name of the vendor that produces this drive enclosure, or box type. Use
this information for identification purposes.
• Model displays the model of the storage system. Use this information for identification purposes.
• Firmware Revision displays the firmware revision of the drive enclosure or box. Use this
information for identification purposes.
• Serial Number displays the serial number of the drive enclosure or box. Use this information
for identification purposes.
• Drive Bays displays the number of drive bays provided by this storage system. If duplexing
hardware is used with the storage system, the drive bay number is less than the number of
physical drive bays in the enclosure.
• Fan Status displays the status of the fan subsystem in the drive enclosure, or box. The following
values are possible:
◦ OK - The fan subsystem is working properly.
◦ Failed - A fan has failed and there are not enough fans in the fan subsystem to keep the
enclosure cool. Check your fan subsystem as soon as possible. Continued operation may
cause failure of the drives.
◦ Degraded - A fan has failed but there are still enough fans in the fan subsystem to keep
the enclosure cool.
◦ Unknown - The Storage Agents do not recognize the status of the fan subsystem. You may
need to upgrade your software.
◦ No Fan - This storage system does not have a fan.
• Power Supply Status displays the status of the redundant power supply. The following values
are possible:
◦ OK - All component power supplies that make up the redundant power supply are in
normal working order.
◦ Degraded - One of the component power supplies that make up the redundant power
supply has failed. The drive system (either a drive subsystem or a power supply for the
main unit) continues to operate. However, if the remaining power supply should fail, the
drive system will lose all power and data loss could occur. To correct this situation,
schedule a time to bring the device down and replace the failed power supply.
◦ Unknown - The Storage Agents do not recognize the redundant power supply. You may
need to upgrade your software.
◦ No Redundant Power Supply - This storage system does not support a redundant power
supply.
