[osol-discuss] Using SPARC formated disks on X86?
I put a SCSI disk originally formated, partitioned, and loaded with data on a SPARC machine, into a X86 machine I just installed NV b74 on. When I run format, I see the disk in the list, and select it, but when I go to check the partition table, format tells me to go run fdisk first. Won't running fdisk destroy the SPARC created data structures on the disk? Is there some process for converting a disk? or for telling SolNV X86 to access it the way a SPARC would? -Kyle ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Format the disk with a zpool / zfs (using an EFI disk label), and both SPARC and x86 can use it.

If you can dd the disk image, I can probably provide you with some tools to find the ddiskpartition and to convert (fsck needed) the partitions to x86 format.

This is more then an FDisk, VTOC issue, in that if one found the UFS partition, it too will be unreadable. If one could read the UFS partition, then the UFS volume header, all inodes, all directories and the contents of some, but not all files would be unreadable.
