Hello, we have a problem with the iscsi initiator on Solaris 10. As soon
as we run it it goes into maintenance. Also iscsiadm does not work.

# iscsiadm list discovery
iscsiadm: unexpected OS error
iscsiadm: Unable to complete operation

Hardware is a Sun V480.
We did an upgrade from Solaris 8 to 10.
SunOS srv01 5.10 Generic_125100-08 sun4u sparc SUNW,Sun-Fire-480R
