USB Floppy Drive Fails to Mount (6650724)
Floppy disks are not automatically mounted when inserted into USB oppy drives. No error
message is displayed. The pcfs le system on the oppy disk is not accessible.
Workaround: The le system on the oppy disk can be mounted manually by running the
mount command. For example:
mount -F pcfs /vol/dev/dsk/c3t0d0/noname /rmdisk

The following error message is displayed when a USB storage device is disconnected:
Disconnected device was busy, please reconnect.
This message is displayed even when the device is unmounted successfully.
Workaround: None. The error message can be safely ignored.
The (ZFS) ARC Allocates Memory Inside The Kernel
Cage Preventing DR (6522017)
ZFS can potentially allocate kernel memory across all system boards on systems with very large
memory congurations. One free system board is required for dynamic memory
reconguration so that the memory from the board to be dynamically recongured can be
copied to the free board. The dynamic memory reconguration means that you cannot
dynamically recongure memory on systems with very large memory congurations that have
ZFS running. High-end SunFire
TM
servers can relocate kernel pages so that this issue is avoided.
These servers must have kernel page relocation (KPR) enabled for domains with more than 32
cores. No error message is displayed
Workaround: Reduce the amount of kernel memory that ZFS can allocate by setting the
zfs_arc_max parameter in the /etc/system le. The following example sets the maximum size
to 512 Mbytes.
set zfs_arc_max = 0x20000000
