Hi,
"Illegal request. An illegal parameter in the command descriptor block or in the additional parameters supplied as data for some commands (for example, the Format Unit command, the Mode Select command and others). If the drive detects an invalid parameter in the CDB, it terminates the command without altering the media. If the drive detects an invalid parameter in the additional parameters supplied as data, the drive may have already altered the media."

then

"A write error occurred, but the error was recovered using auto-reallocation."
or
"A write error occurred. Auto-reallocation was attempted, but it failed."

Either way, check your disk !

Hi,

Since you have got EMS events have you verified /var/opt/resmon/log/event.log file.

That will throw you some light.

Thanks,
