init 6 hangs on zpool using iSCSI LUNs with Solaris 11 (Doc ID 1420863.1)

Last updated on JANUARY 05, 2023

Applies to:

Solaris Operating System - Version 11 11/11 to 11 11/11 [Release 11.0]
Solaris Operating System - Version 11 u1 10/12 to 11.1 [Release 11.0]
Information in this document applies to any platform.


"init 6" command hangs, however "reboot" command works without issues.

If the problem is encountered, sending a break to the system will show a thread with the following stack:
