常æ æ æ ²å¿ , do you still have internet access in China? (we have heard rumors that internet connectivity is limited)

Check your hardware. Check connections. Maybe your hardware is not properly connected / powered on maybe? Where are located the disks you are talking about? Are those internal disks?

Cháng yÇ u cíbÄ i xÄ«n,

What kind of disk?
Is there an array? What make and model? If array, has it been zoned/mapped/masked properly?

Please supply all the requests for additional information, so we may help you.

Please attach ioscan -fn o/p
What is the type of LUN
internal / external disks?

you need to run
