Trouble mounting after installing hard drives.

I recently installed some SAS drives into our AX4-5 and we are now experiencing the following error:

Error 2237: Execution failed: have_disk_group: Precondition violated. [VIRTUAL_DISK.is_spindle_type_mixed]

This error appers after I run the following command in an attempt to discover the new storage that I have installed in the arrays:

nas_diskmark -mark -all server_2 -discovery y

As the title states we are having problems mounting directories now as all. All this comes after we installed the new hard drives. I have already figured that directories should have been unmounted prior to installing (they were not) but now we can't seem to get things back to working and I can't find any information on this error for the life of me. If anyone has any ideas on where to start troubleshooting it is greatly appreciated. Unfortunately I can't post logs or anything like that since I am in a secret facility.
