I have an IBM x series and when i try to boot it shows me this message.
Please can anyone tell me what is the cause and how can resolve the problem.
When getting Raid Status failed most of times it is necessary to reestablish the volume since the structure failed. I see you have a raid 1 so you can try setting the System to non raid from CTRL-I.
You are going to get a notification that all information will be lost but on RAID 1 this does not apply. You can set it to non raid and all information will be on both HDD and you should be able to boot into the HDD without a problem.
