if checking status of a device, it shows some paths in asb:iopf dead, that is cause due to an error in the SAN network, that affect the path shwoing this status.
root@solaris :/root # powermt display dev=emcpower2a

This example will show an ASCII progress bar with information about speed of the I/O. When dd will finish it will keep showing the results.
# dd if=/dev/urandom | pv | dd of=/dev/null
below example will use a nice dialog with the message between quotes
# (pv -n /dev/uramdom | dd of=/dev/null bs=128M) 2>&1 | dialog --gauge "Running dd command (cloning), please wait..." 10 70 0
If checking status of powermt you see some in unlic state, here is how you can solve it.
First, check on license status, it has to show a valid license.
# powermt check_registration
then run the following command to set the policy to all devices.
# powermt set policy=so dev=all
Sometimes I get a stuck Virtual Machine that just won't go down and it's usually due to a lack of memory in the VM. When I issue a shutdown command from within the VM it starts the shutdown process but hangs part way through. Executing xe vm-shutdown uuid=<insert UUID here> --force does nothing but lock up the terminal. If this happens to you follow the steps below to forcefully shut the VM down. WARNING!! Only do this as a last resort.

In order to convert the Solaris ssd naming from sd# to c#t#d#, very useful as in the log files will be showed only the sd# naming, we can use the next simple set of commands to convert them.
# paste -d= <(iostat -x | awk 'NR>2{print $1}') <(iostat -nx | awk 'NR>2{print "/dev/dsk/"$11}')
this the output for some disks:
sd0=/dev/dsk/c0t5000CCA0164B7CDCd0
sd1=/dev/dsk/c0t5000CCA0164BD734d0
sd4=/dev/dsk/c1t0d0
ssd0=/dev/dsk/c4t5000097500015190d6
ssd1=/dev/dsk/c4t5000097500015190d5
