Explanation

You might need to replace a disk in the root pool for the following reasons: The root pool is too small and you want to replace it with a larger disk The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot, you'll need to boot from an alternate media, such as a CD or the network, before you replace the root pool disk. In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to boot from alternate media. You can replace a failed disk by using the zpool replace Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace operation to replace a failed disk. # zpool offline rpool c1t0d0s0 # cfgadm -c unconfigure c1::dsk/c1t0d0 <Physically remove failed disk c1t0d0> <Physically insert replacement disk c1t0d0> # cfgadm -c configure c1::dsk/c1t0d0 # zpool replace rpool c1t0d0s0 # zpool online rpool c1t0d0s0 # zpool status rpool <Let disk resilver before installing the boot blocks> SPARC# installboot -F zfs /usr/platform/uname -i/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0 x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t9d0s0
