Solaris LDOM's Back-up and Restoration Procedure

-

How to add vdisk to Guest LDOM:


#ldm ls -e -l -o disk|grep san|sed 's/primary-vds0//'|awk '{print "ldm add-vdsdev",$2, $1"@primary-vds0"}' > Virtualdisk.out_`date +%d%m%y`


LDOM Migration from One node to another Node:

#for i in `ldm ls |awk '{print $1}' | egrep -vi "name|primary"`;do ldm migrate -p pswd $i ldmadmin@targetserver


How to set the Host ID for Guest LDOM:


#ldm set-dom hostid=82a85641 ldom1


How to restore the Guest LDOMs from XML Files:


#for i in `ls -l |grep xml|awk '{print $9}'|egrep -iv primary`; do ldm add-domain -i $i ;done


How to Bind the Guest LDOM:


#for i in `ldm ls |awk '{print $1}' | egrep -vi "name|primary"`;do ldm bind $i ; done

How to start the Guest LDOM


#for i in `ldm ls |awk '{print $1}' | egrep -vi "name|primary"`;do ldm start $i;done



Single  Guest LDOM Restoration steps:

#ldm add-domain -i domainname.xml
#ldm bind domainname
#ldm start domainname


Note: we need to remember one thing when we restore Guest domains from xml file , we need to import the zpool if we have anything in the Guest domain.

Taking xml backup of Guest domain(LDOM):


#ldm list-constraints -x  ldom > ldom.xml

Veritas Cluster Server (VCS) Commands - Cheat Sheet

 LLT and GRAB VCS uses two components, LLT and GAB to share data over the private networks among systems. These components provide the performance and reliability required by VCS. LLT LLT (Low Latency Transport) provides fast, kernel-to-kernel comms and monitors network connections. The system admin configures the LLT by creating a configuration file (llttab) that describes the systems in the cluster and private network links among them. The LLT runs in layer 2 of the network stack GAB GAB (Group membership and Atomic Broadcast) provides the global message order required to maintain a synchronised state among the systems, and monitors disk comms such as that required by the VCS heartbeat utility. The system admin configures GAB driver by creating a configuration file ( gabtab). LLT and GAB files /etc/llthosts --> The file is a database, containing one entry per system, that links the LLT system ID with the hosts name. The file is identical on each server in the cluster. /etc...

Oracle Logical Domains (LDOM) Back up & Restoration from Backup Files

-
Saving Domain Configurations for Future Rebuilding The basic process is to save the resource constraints information for each domain into an XML file, which can then be re-issued to the Logical Domains Manager, for example, after a hardware failure to rebuild a desired configuration. Restore a Domain Configuration From an XML File ( ldm add-domain )  works for guest domains, but not for the control ( primary ) domain. You can save the  primary  domain's constraints to an XML file, but you cannot feed the file back into the  ldm add-domain -i  command. However, you can use the  ldm init-system  command and the resource constraints from the XML file to reconfigure your  primary  domain. You can also use the  ldm init-system  command to reconfigure other domains that are described in the XML file, but those domains are left inactive when the configuration is complete. The method that follows does not preserve actual bindings, only the ...
