On a Sun Fire[TM] 12K/15K/E20K/E25K domain, an attempt to DR out a System Board which contains permanent memory results in the domain becoming hung. The last entry in the domain's /var/adm/messages file or console log indicates that the domain is attempting to resume an I/O device driver. Even after over an hour, the domain is still unresponsive and remains at this device resumption stage.
NOTE: When DR'ing a System Board that contains permanent memory out of a domain, the Soalris[TM] OS is suspended temporarily to allow for the reallocation of the permanent memory to other System Board resources which will remain in the domain. This suspension is not the "hang" described in this document.

The domain's console log shows the following (SB7 is the board which contains permanent memory):

Aug  5 01:05:46 2004 root@domainA # cfgadm -v -c disconnect SB7
Aug  5 01:05:49 2004 System may be temporarily suspended, proceed (yes/no)? yes
Aug  5 01:05:49 2004 request suspend SUNW_OS
Aug  5 01:05:51 2004 request suspend SUNW_OS done
Aug  5 01:05:51 2004 request delete capacity (4 cpus)
Aug  5 01:05:51 2004 request delete capacity (1048576 pages)
Aug  5 01:05:51 2004 request delete capacity SB7 done
Aug  5 01:09:11 2004    resuming pci108e,8001@3d,600000 (aka pcisch)
Aug  5 01:09:11 2004    resuming JNI,FCR@1,1 (aka jnic146x)
Aug  5 01:09:12 2004    resuming JNI,FCR@1 (aka jnic146x)

In the example above, the domain was forced to the OBP via the reset command.
