14, the maintenance command set of the double machine
First start the cluster: # SCADMIN STARTCLUSTER SMCP01 SMCP on the node SMCP01, then start this node on the node SMCP02: # SCADMIN STARTNode Starting Observing the CLUSTER status command is: # Hastat // This command can display cluster, nodes, logic, and Data service's status, as well as some historical operations.
# get_node_status // This command can display information such as the node number and public network card of the node.
From the graphical local terminal (assuming its IP address is IP), log in to the SMCP host as SMCP user (note that the logic address of SMCP)% Telnet SMCPWork sets environment variables on the SMCP host to DISPLAY% STENV Display IP: 0.0 Performing% XHOST Manual Start OAM% OAM & Login with OAM Operator
Performed on two nodes SMCP01 machines and SMCP02: # SCADMIN stopNode This command will stop the current node to run in the Cluster and execute the command separately on both nodes.
For example, running SMCPWork to node SMCP02 can be entered: #scadmin Switch SMCP SMCP02 SMCPWORK, for example, running QueryWork to node SMCP02 can be entered: #HASWITCH SMCP02 QueryWorkhareg Command The Data Service Register and activate -R will be specified by the following switch parameters Data Service Register to Cluster -u to unregister the specified Data Service from the Cluster to activate the specified Data Service so that the status is ON -Y to activate all Data Service in the Cluster to activate its status. The specified Data Service enables its status to activate all the Data Service in the Cluster so that the status of all Data Service can be viewed for any parameter without any parameters. After registering to the Cluster, The status of ON or OFF will be available in the ON state, and the DATA Service in the OFF state is a normal external service. If the Data Service is canceled, you must re-register to run in Cluster. Of course, the premise of using the Hareg command is that the Cluster has started and running normally.

16. SUN Netra T 1125 Detailed annotations for dual-machine configuration
A. Configuration of Network Resources Sun Netra T 1125 has 4 NIC: HME0, HME1, HME2 and HME3. HME0 and HME1 are the SUN server and the owner network card of the public network. It only needs an IP address; HME2 and HME3 are used as the heartbeat detection between the dual-machine, but also need to configure an IP address. In addition, TELLIN SMP external use is a floating IP address, with data IP in the same network segment, which is managed by Sun's Dual Software Sun Cluster.
1) How to modify the IP address and host name
The files involved in the IP address include: / etc / hosts (Change the ip address) / etc / netmasks (if subnetting) / etc / default (to Specify The New Gateway for this subnet)
Change the files involved in the host name: / etc / hosts (change to the new hostname) / etc / hostname.
Just give the HME0 configuration address is enough. This relationship is created when the following command is created in the next duplex configuration. #scconf smcp -l smcpwork -n smcp01, smcp02 -g smcpdg -i HME0, HME0, SMCPWORK -M
3) Configuring NAFO (NETWORK Adapter Fail over) / OPT / SUNWPNM / BIN / PNMSET
Check nafo0 ... <20 second hme0 is active remote address = 129.9.168.101 Test HME1 WAIT ... NAFO0 Test Passed this information indicates that the NAFO configuration is high when the NAFO configuration is high, sometimes it is necessary to successfully .
B, the general process of configuring the dual-machine configuration is, first start the dual-machine system, configure Cluster and bag on a node, check the configuration, and then make the appropriate operation. Note: Check the status of SMCPDG, QueryDG before using the double-machine. Perform the following steps: (1) Execute them separately in the two nodes: # vxdg list Should only see rootdg and cannot see SMCPDG and Querydg. (2) If the SMCPDG or QueryDG is stepped on step by step, it is necessary to check if the IDS is running (ONLINE). If you are running, terminate the IDS before running, then discard the control of Disk Group using vxdg deport. ==================== The general process of the two-machine configuration is to start the dual-machine system first, configure Cluster and packs on a node, after checking, make the configuration take effect , Then you can do it accordingly. Note: Check the status of SMCPDG, QueryDG before using the double-machine. Perform the following steps: Execute the two nodes separately: # vxdg list Should only see rootdg, you can't see SMCPDG and Querydg. If you see SMCPDG or Querydg on a step, you need to check if the IDS is running (Online). If you are running, terminate the IDS before running, then discard the control of Disk Group using vxdg deport.
Configure the two-machine system to run the #scadmin StartCluster SMCP01 SMCP. After the 2-machine software, run #scadmin startnode at No. 2 machine, add it as a node to the two-machine configuration logic to the two-machine system logic, which corresponds to the application, is a dual-machine system management application. Ways, each logic is only available outside the dual-machine system. ================================================= (2 Configure Cluster to run on a host #SCCONF IIN -L SCPWORK-N SMCP02, SMCP01 -G scPDG -I HME0, HME0, SCPWORK -M Note: SCCONF
Remarks: The floating IP address of the host name of the logic here must be configured in the / etc / hosts file.
To establish a management file system on each machine # Scconf Iin -f SCPWORK SCPDG Note: This command format is: Scconf
Establish management file system # scconf Iin -f querywork querydg
Register Double Machine HEREG -U Querywork Query.Register
HEREG -U SMCPWORK SMCP.REGISTER
C, configure the application
The / etc / opt / sunwcluster / conf directory can view the two files of the CCD.DataTBase and SmCP.cdb to view the information of the two-machine basic configuration and the Cluster, do not handle these files to keep the system to maintain them. Where ccd.Database has a special daemon maintains the same consistency on two nodes.
/ OPT / SUNWCluster / HA directory contains both SMCP and Query two subdirectories. The SMCP directory stores the Data Service-related profile and execution script of the SMCP section, where the smcp.config file records the basic configuration of the SMCPWork, and the smcp.register is used to register SMCPWork, and the other files are started, stop and monitor the run script of SMCPWork. The query directory stores the Data Service related configuration file and execution script in the Query section, where the query.config file logs QueryWork's basic configuration, Query.Register is used to register Querywork, and other files are required to run scripts. When you join the two Data Service to the Cluster, you must be registered via the Hareg command, which is already completed by executing smcp.register and query.regs during installation.
Remarks: The file ccd.database in the conf directory can cause the dual-machine to switch properly if the two machines are inconsistent.
D, two-machine configuration test
(1) Running on the host #scadmin startcluster smcp01 smcp (2) Waiting for the host dual-machine software to run on the standby machine #SCADMIN STARTNODE (3) running DF-K and ifconfig -a test in two hosts Run Hastat to view the HA status, you can see the HME0 bundled SMCP, Query application floating IP: HME0 .... 129.9.168.9.168.120 HME0: 2 .... 129.9.168.140 ( 4) Use the Haswitch command to switch the experiment, switch the logical host SMCPWORK by the physical host SMCP01 to the physical host SMCP02. # HASWITCH SMCP02 SMCPWORK To see if it is successful, then the following method: View disk resources with DF -K on the host SMCP02. If the display information has the following, the switching success: / dev / vx / dsk / smcpdg / smcpdg-stat to view the IP address on the host SMCP02, if the logical host SMCPWork's IP address 129.9.169.120 is tied The handover is successful in the HME0 NIC (the main network card of the public network).

=====================================
In Tellin SMP's Sun Netra T1125 standard configuration, the host is a Sun server without a display card and a display, so use the terminal hub to display the two hosts on the console signal to the monitoring station. Since the host is not controlled before Solaris is not started, the terminal hub must be set first. If the Terminal Concentrator (TC) is already set, you can reset it. The configuration steps of the terminal hub are given below. Once the terminal hub is configured, there is no need to configure each time. The following configuration procedure assumes that the IP address of the TC is 129.9.168.23, and the subnet mask is 255.255.255.0.
(1) Use a Sun workstation to connect the port 1 of the serial port A and the terminal hub with the RS232 J45 cable. Plus: A: DV = / demote file: a: DV = / dev / term / A: BR 9600: EL = ^ c ^ s ^ ^ u ^ D: IE =% $ E = ^ D: EL = ^ C ^ s ^ Q ^ U ^ D: IE =% $ E = ^ D: (2) Type: TIP A (3) Correctly connecting the terminal hub and public network (4) Correctly connect the terminal hub (5) ) Press the Test key of the terminal hub, the TEST indicator lights and enters the test mode. Note: Press the TEST button immediately after the power light is on, and cannot wait until it enters the normal running state, which is equivalent to "DEL" in the computer to enter the setting status. After completing the test, the correct indicator status is shown in Table 2-2. Table 2-2 Terminal Hub Indicator Lamp Name Power Unit Net Attn Load Active Colors Green Green Green Amber Green Green Status ON ON OFF OFF Slow (6) The monitor :: prompt will appear on the Sun workstation, use the addr command Configure TC's IP and subnet screen Monitor :: Addr
(Turn off the terminal hub power and reboot, if the PC function is used to Telnet, the correctness of the above configuration is verified. At this point, the port of the terminal hub is configured: Telnet 129.9.168.23
