[OpenIndiana-discuss] get no system dumps: skipping system dump - no dump device configured

[Carsten Grzemba]

I try to investigate boot hangs with latest hipster. Unfortunately "send break" is not possible on X4200 and dump after NMI is not working, however dumpadm shows:

$ sudo dumpadm 
Password: 
 Dump content: all pages
 Dump device: /dev/zvol/dsk/rpool/dump (dedicated)
Savecore directory: /var/crash/gnom
 Savecore enabled: yes
 Save compressed: on

and:
$ zfs list rpool/dump
NAME USED AVAIL REFER MOUNTPOINT
rpool/dump 8.00G 310G 8.00G -


Any ideas why system after NMI means dump devices is not configured 

Many thanks
