Kernel Modules Cannot Be Unloaded (Doc ID 1536763.1)

Last updated on APRIL 06, 2021

Applies to:

Solaris Operating System - Version 10 10/09 U8 to 10 9/10 U9 [Release 10.0]
Information in this document applies to any platform.


In some cases trying to "modunload" kernel modules fails with "can't unload the module: Device busy", for no obvious reason, in some versions of Solaris 10.


A prerequisite for this bug is that the svc:/network/iscsi/initiator:default service has been disabled.

# svcs -a | grep iscsi
disabled       Dec_31   svc:/system/iscsitgt:default
disabled       Jan_03   svc:/network/iscsi/initiator:default
