I did not backup the configuration after two disks were replaced in a logical drive.
So, when the Xyratex F5404E lost its configuration (long story), the previous binary configuration file did not know about the two newer disks.
It was looking for the previous two disks (based on serial number).
Had I backed up after replacing the two disks, I would not have this problem. The SES would know that it should use the two newer disks as part of the logical drive/RAID.
I thought that I could replace the two old serial numbers in the binary file, put in the new serial numbers and then re-upload it to the SES (StorView) of the F5404E.
This did not work.
I received the following error message:
"(05/26/00) Invalid field found in parameter list. Return to main screen and retry operation."
I don't know what else might need to be changed in the binary file. I used a Hex editor to edit the binary file and change the two serial numbers. I hoped that it would be enough. Since I don't know the format of the binary file, I am obviously stuck. I have no way to tell it that the logical drive/RAID will work fine if it uses the newer disks which have existing data on them.
