PS6000 FIX RAID
I couldn't reach my array disk PS6000 while pinging
So i tried to reboot it but the LED's of RJ45 ports are off
I tried to connect it using console serial port
i think that my array disk couldn't boot => RAID problem
Is there any solution to fix raid
Can i backup all the volumes on an externel harddisk ?

Hello,
The answer is no. You are not understanding how RAID works. The files are not stored individually on each drive. The data is spread across all the drives. Depending on the RAID level either one or two drive failures can be tolerated. More than that the RAIDset has faulted beyond its ability to be online.
https://en.wikipedia.org/wiki/Standard_RAID_levels
Which is why I pointed you to a data recovery service. If they can restore enough data from the failed drives the RAIDset will come back online. Then you can access your data and back it up.
Regards,
Don

It is not necessary to make recovery the way server should come online. Data could be recovered out of the shelf, raid and EQL part could be emulated by software. Only hdd acccess through any HBA controller is need, and of course, affected drives should be imaged.
