I have a Sun Storage 6140 for testing but it has only one controller and another one is blank and also has high firmware version. And I have another Sun Storage 6140 in production that has low firmware version.
Now Sun Storage 6140 in production has one faulty hard disk, so I want to take one hard disk from Sun Storage 6140 for testing to replace it but it cannot running because hard disk on Storage test has firmware not match with Storage in production.
That why I want to downgrade firmware on Storage test to match with Storage in production.
Thank you very much for your help and prompt reply.
Now I don't downgrade FW yet. I want give more info on this problem as below:
I have storage (A) and storage (B)
- Storage (A): has one faulty hard disk and all hard disk has firmware low version
- Storage (B): all hard disk has firmware high version
I try many time to take one hard disk from storage(B) to replace a faulty hard disk on Storage (A), after replacement I see the status on hard disk is blue but not recognize and checking status in CAM is still fail, I don't know why?
Array firmware downgrade is neither qualified nor supported by Oracle, this is why such procedure cannot be delivered publicly.
Beside that, the 6140 must contain two controllers, it is not supported to have only one controller in a 6140. If you correct this configuration and if you still need assistance due to a bug that requires you to downgrade the firmware, please open a Service Request with the Oracle support and we will evaluate the situation.
Please be informed that we have the "Storage Disk 2000, 3000, 6000 RAID Arrays & JBODs Community (https://communities.oracle.com/portal/server.pt/community/storage_disk_2000%2C_3000%2C_6000_raid_arrays___jbods/465) where you can post technical questions.
I will make more clear about this and what I have done for this problem.
- (A) Storage has a hard disk faulty has controller firmware version as below (2 controllers)
- (B) Storage that need to take a hard disk to replace a faulty hard disk above and has only 1 controller
I have tried to erase the DACstore on the drive and than replace with a faulty hard disk but not fix this problem, so I suspect on controller firmware and I want to downgrade controller firmware of storage B to compatible with controller firmware on Controller A.
Please kindly give advice or other solution for this.
