Hardware Installation And Configuration Issues; Address Initial Start-Up Issues - Seagate Exos X 4006 Series Hardware Installation And Maintenance Manual

9 Hardware installation and configuration issues

The storage enclosure management interface allows for provisioning, monitoring, and managing the storage 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 Seagate 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. Refer to
enclosure fault LEDs" on the next page
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.
c. Power cycle the storage enclosure.
d. Examine the controller module system log for errors.
