9 Hardware installation and configuration issues
The storage enclosure management interface allows for provisioning, monitoring, and managing the
enclosure. It uses the storage enclosure processor (SEP) and associated monitoring and control logic, such as
the SCSI Enclosure Services (SES) service, or Redfish, to assess and diagnose power, drive modules, and
cooling systems. Temperature sensors throughout the enclosure and its components monitor the thermal
health of the storage system. If a critical sensor value exceeds a threshold limit, you receive a system
notification that requires your attention.
If you encounter any issues during installation or initial configuration, use the topics in this section to assist you
in fault isolation and correction.
IMPORTANT Do not use this section for configured systems already interacting with production data. For
the kind of assistance you need in such cases, contact Quantum for technical support.
Address initial start-up issues
You must successfully complete the installation tasks in the identified sequence. You must use the power
cords provided with the system and install interface cables that meet system requirements.
To address initial start-up issues:
1. Complete the following actions to eliminate POST issues:
a. For dual controller configurations. wait a minimum of 10 minutes for each controller to complete
synchronization with the other controller and to reach a ready state.
b. For single controller configurations, wait a minimum of 2 minutes for the storage enclosure to reach a
ready state.
2. Complete the following actions to eliminate power cord issues during installation:
a. Request a replacement for damaged or missing power cords.
b. Request a replacement for cords with plugs that do not match your outlets or voltage requirements
c. Request a replacement for power cords that are too short to reach a power distribution unit.
3. Use LEDs throughout the storage enclosure as a means to determine if there is a critical fault. See
and 2U24 enclosure fault LEDs" on the facing page
or
"5U84 enclosure fault LEDs" on page 74
4. Complete the following actions to verify your installation if the host system does not recognize the storage
enclosure:
a. Verify the interface cables you connected from the storage enclosure to each host bus adapter are not
damaged, loose, or wired improperly.
b. Look for any host connection indicators on both controller modules.
c. Look for drive or disk group target visibility on the host side.
d. Verify you correctly installed the operating system software driver.
5. Complete the following actions if the storage enclosure does not initialize:
a. Verify each power cord is properly and securely connected on both ends.
b. Reconfirm that the power source used to power the storage enclosure, is viable, and meets the
installation criteria.
