Sun SPARC Enterprise M-Series Servers Configuration Concepts
This Sun BluePrints article covers basic and advanced configuration concepts and goes through several sample configurations for Sun SPARC Enterprise M4000, M5000, M8000, and M9000 servers.
Good Day,
We have bought Sun Sparc Enterprise T5120 with pre-installed Solaris 10 Sparc
But i need on this server Solaris 9. I have inserted in to DVD-rom (USB DVD-rom) with Solaris 9 for Sparc.
Then log into shell and type: reboot -- cdrom.
System rebooted and i have this message:

Hello,
Wondering if anyone can help me with mounting a file share from my Sun T2000 server running Solaris 10 to my connected 2530 disk array?
I believe I've connected the disk array correctly and I have created a volume on the array using the filesystem (Sun_SAM-FS, RAID-5).
The T2000... (15 Replies)
Hi,
I have Sun SPARC Enterprise T5140 and I can't access it via serial port using preconfigured administrator account, as described in Sun Integrated Lights Out Manager 2.0 User's Guide: I'm always receive "Login incorrect" message. I'm really confused! Does anyone experience such circumstances?... (12 Replies)
dcs(1M) System Administration Commands dcs(1M)NAME
dcs - domain configuration server
SYNOPSIS
/usr/lib/dcs [-s sessions]
[ [-a auth] [-e encr] [-u esp_auth] ] [-l]
DESCRIPTION
The Domain Configuration Server (DCS) is a daemon process that runs on Sun servers that support remote Dynamic Reconfiguration (DR)
clients. It is started by the Service Management Facility (see smf(5)) when the first DR request is received from a client connecting to
the network service sun-dr. After the DCS accepts a DR request, it uses the libcfgadm(3LIB) interface to execute the DR operation. After
the operation is performed, the results are returned to the client.
The DCS listens on the network service labeled sun-dr. Its underlying protocol is TCP. It is invoked as a server program by the SMF using
the TCP transport. The fault management resource identifier (FMRI) for DCS is:
svc:/platform/sun4u/dcs:default
If you disable this service, DR operations initiated from a remote host fail. There is no negative impact on the server.
Security for the DCS connection is provided differently based upon the architecture of the system. The SMF specifies the correct options
when invoking the DCS daemon, based upon the current architecture. For all architectures, security is provided on a per-connection basis.
The DCS daemon has no security options that are applicable when used on a Sun Enterprise 10000 system. So there are no options applicable
to that architecture.
The security options for Sun Fire high-end systems are based on IPsec options defined as SMF properties. These options include the -a auth,
-e encr, and -u esp_auth options, and can be set using the svccfg(1M) command. These options must match the IPsec policies defined for DCS
on the system controller. Refer to the kmd(1M) man page in the System Management Services (SMS) Reference Manual. The kmd(1M) man page is
not part of the SunOS man page collection.
Security on SPARC Enterprise Servers is not configurable. The DCS daemon uses a platform-specific library to configure its security options
when running on such systems. The -l option is provided by the SMF when invoking the DCS daemon on SPARC Enterprise Servers. No other secu-
rity options to the DCS daemon should be used on SPARC Enterprise Servers.
OPTIONS
The following options are supported:
-a auth Controls the IPsec Authentication Header (AH) algorithm. auth can be one of none, md5, or sha1.
-e encr Controls the IPsec Encapsulating Security Payload (ESP) encryption algorithm. encr can be one of none, des, or 3des.
-l Enables the use of platform-specific security options on SPARC Enterprise Servers.
-s sessions Sets the number of active sessions that the DCS allows at any one time. When the limit is reached, the DCS stops accepting
connections until active sessions complete the execution of their DR operation. If this option is not specified, a default
value of 128 is used.
-u esp_auth Controls the IPsec Encapsulating Security Payload (ESP) authentication algorithm. esp_auth can be one of none, md5, or sha1.
EXAMPLES
Example 1 Setting an IPSec Option
The following command sets the Authentication Header algorithm for the DCS daemon to use the HMAC-MD5 authentication algorithm. These set-
tings are only applicable for using the DCS daemon on a Sun Fire high-end system.
# svccfg -s svc:/platform/sun4u/dcs setprop dcs/ah_auth = "md5"
# svccfg -s svc:/platform/sun4u/dcs setprop dcs/esp_encr = "none"
# svccfg -s svc:/platform/sun4u/dcs setprop dcs/esp_auth = "none"
# svcadm refresh svc:/platform/sun4u/dcs
ERRORS
The DCS uses syslog(3C) to report status and error messages. All of the messages are logged with the LOG_DAEMON facility. Error messages
are logged with the LOG_ERR and LOG_NOTICE priorities, and informational messages are logged with the LOG_INFO priority. The default
entries in the /etc/syslog.conf file log all of the DCS error messages to the /var/adm/messages log.

dr(7D)NOTES
The dcs service is managed by the service management facility, smf(5), under the fault management resource identifier (FMRI):
svc:/platform/sun4u/dcs:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
