zpool attach Command Does Not Copy bootblock
Information (6668666)
If you use the zpool attach command to add a disk to a ZFS root pool, the bootblock
information is not copied to the newly added disk. This problem does not aect mirrored ZFS
root pools that are created with an initial installation. System does not boot from alternate disk
in the mirrored root pool.
Workaround: Choose one of the following workarounds:
■
On a SPARC system, identify the alternate disk device and install the boot information. For
example:
# installboot -F zfs /usr/platform/‘uname -i‘/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0
■
On an x86 system, identify the alternate disk device and install the boot information. For
example:
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t1d0s0
x86: ata Timeouts During Boot (6586621)
ata driver timeouts might occur during system boot on Intel multiprocessor systems. These
timeouts occur when the root device is on a drive with the HBA controller bound to the legacy
ata driver. These timeouts lead to a momentary hang, hard hang, or a panic during system boot
with console messages similar to the following:
