Hello Managers,
I try to bulid mirror of root file system, /usr and swap on my ultra
5 machine. i change alias for primary boot-device to secondary
boot-device using nvalias command
i put this command on ok prompt
nvalias backup_root /pci@1f,0/pci@1,1/ide@3/dad@2,0:a
boot backup_root
and get error like this
can not open boot device
/dev/dsk/c0t2d0s0 refer to /devices/pci@1f,0/pci@1,1/ide@3/dad@2,0:a
and this is the configuration for mirror
root@potato: /#metadb
flags first blk block count
