When the server does not recognize the disks
When the server does not recognize the disks, points to be checked depend on the situation.
• All servers do not recognize the disks
• Check the status of the ETERNUS DX60/DX80/DX90 and other devices such as network
devices connecting the server and the ETERNUS DX60/DX80/DX90, and ensure that there
are no problems with the power supply.
• Check if the drive enclosure is turned on. If the drive enclosure is not turned on, check if the
miniSAS cables (for drive enclosures) are connected. If the miniSAS cables are not
connected, connect them with the following procedure.
• Specific servers do not recognize the disks
If the specific servers do not recognize the disks (while other servers can), check the following
points. If none of these resolve the problem, leave the ETERNUS DX60/DX80/DX90 alone
and contact your maintenance engineer.
