My array disk PS6000 is failed
and it couldn't see the physical disks after restarting the array disk's led are off
i got a critical data on those disks
Can i use my PS4000 and connect my disks on it in order to extract my data from it ?
No. I do not see any other solution. Too many drives have failed to keep the RAIDset alive. Drive recovery could recover enough data to get the RAIDset back online. Which would allow you to access your data. Your data is not stored in "files" on an NTFS partition that can just be read individually.
I am sorry you feel disappointed and given the situation I can understand how stressed you are but let's review a few things.
