Solution  1008803.1 :   Sun Fire[TM] 12K/15K: showdevices can hang if sd.conf is large or misleading  


PreviouslyPublishedAs

Symptoms
After issuing the command 'showdevices -d <domain id>' or 'showdevices -v', the expected output takes a significant amout of time to be displayed. In most cases, 'showdevices' will appear hung.


The following messages might be logged in the domain level messages file on the SC ( $SMSVAR/<domain>/adm/messages ) or into the /var/adm/messages file on the domain.

Feb 8 12:41:37 2002 my15k-sc0 dca[23562]-A(): [4318 1969817969955841 ERR

ConsoleService.cc 1471] HWAD getFlag(valid=0x1) from iosramp BUSY!! (key: 0x434f4e49)

Resolution
The problem is actually not with the 'showdevices' command that runs on the System Controller (SC), but with the domain configuration server (DCS) that resides on the domain.

DCS provides support for remote dynamic reconfiguration (DR) clients that run on the SC such as 'showdevices'. The command 'showdevices' relies on /usr/lib/dcs to display the configured physical devices on system boards and the resources made available by these devices. If /usr/lib/dcs has to initiate a system call to other daemons for every entry in the sd.conf file, and the sd.conf file is quite large and/or has entries for devices that don't actually exist, it can take a large amount of time for 'showdevices' to complete.

The solution to this problem was to make /usr/lib/dcs smarter and reduce the number of external system calls required for it to gather the requested information. To avoid this problem, install one of the following patches on the domain:

Patch 111332-06 () for Solaris 8[TM]

Patch 114326-01 () for Solaris 9[TM]
