I just did my first run on sles11sp4 → sles12sp1 upgrade.
My host is a HP hw box, and I booted on the sles12sp1 dvd, select Upgrade. I get to the screen to “Select system to upgrade”, which does not shown anything - tick at “Show all partitions” shows a lot of partitions (the host being a hypervisor host).
My disk layout for the host is:
[CODE]Model: ATA ST2000DM001-1CH1 (scsi)
Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 4294MB 4293MB primary linux-swap(v1) raid, type=fd
2 4294MB 541GB 537GB primary ext3 boot, raid, type=fd
3 541GB 2000GB 1459GB extended lba, type=0f
So the / is on a linux raid build from sda and sdb. But does not seem to be recognized?
