How to clear fmadm log or FMA faults log

Here are the step by step of clearing the FMA faults on most of Oracle/Sun server. Work perfectly on Solaris 10:
Clear fmadm log, Example :
———————————-
For each fault listed in the ‘fmadm faulty’ run:
# fmadm repair <uuid>   (OR if the components are listed instead, e.g.
# fmadm repair 568a9180-7308-4535-92e6-a7c17ef1bfef
[Clear ereports and resource cache:
# cd /var/fm/fmd
# rm e* f* c*/eft/* r*/*
[Clearing out FMA files with no reboot needed:
svcadm disable -s svc:/system/fmd:default
cd /var/fm/fmd
find /var/fm/fmd -type f -exec ls {} \;
find /var/fm/fmd -type f -exec rm {} \;
svcadm enable svc:/system/fmd:default
[Reset the fmd serd modules:
# fmadm reset cpumem-diagnosis
# fmadm reset cpumem-retire
# fmadm reset eft
# fmadm reset io-retire


V=This is a very useful blog post, use it when fmd service is out of sync with syslogd and fmadm clear is not working properly.
On some system this step is explicit about what is being removed:
cd /var/fm/fmd
rm errlog fltlog ckpt/eft/* rsrc/*
line above replaces find /var/fm/fmd -type f -exec rm {} \;

Oracle VM SPARC – LDOM configuration Backup and Restore

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 LogicalDomainsManager, for example, after a hardware failure to rebuild a desired configuration.

 Recently we had an activity where we have to shutdown the /SYS or the control domain. We have forgot to save the configuration to SP so when /SYS was brought up we lost the configuration. It was huge configuration so we had tried to recover it in different ways. We had a back up copy but that didn't work and gave file corruption errors. It is very important to remember that every time explorer runs it saves a copy of the domain configuration. We recovered it from explorer.

1. Login to control Domain and list the current configuration file.

-bash-3.2# ldm list-spconfig

factory-default

config_new [current]

-bash-3.2#

2.To take the complete LDOM configuration backup,use below command.

# ldm list-constraints -x >config.xml

3.You can also  take the configuration backup for specific LDOM,

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

How to restore the system to factory default ?

1. Login to the control domain console and remove the spconfig profile.

bash-3.2# ldm ls-spconfig

factory-default

config_new [current]

bash-3.2# ldm  remove-spconfig config_new

bash-3.2# ldm ls-spconfig

factory-default [next poweron]

bash-3.2#

2.Power cycle the server to take the changes effect.

bash-3.2# init 5

bash-3.2# svc.startd: The system is coming down.  Please wait.

svc.startd: 101 system services are now being stopped.

 Restoring the sp-config :

1.Once the system has restored to the factory default,then you can restore the system backup using the XML files which we have created. Login to the control domain and restore it.

 # ldm init-system -i config.xml

 # ldm add-spconfig unixarencfg1

 # ldm list-spconfig

factory-default

unixarenacfg1 (current)

2.To restore the specific ldom/primary domain configuration

# ldm init-system -i ldom_name.xml

# ldm add-spconfig unixarencfg2

# ldm list-spconfig

factory-default

unixarenacfg1

unixarenacfg2 (current)

3.To restore only the virtual service,

# ldm init-system -s -i filename.xml

-bash-3.2# ldm list-spconfig

factory-default

unixarenacfg1

unixarenacfg2[active on Reboot]

-bash-3.2# ldm add-spconfig unixarencfg3

-bash-3.2# ldm list-spconfig

factory-default

unixarenacfg1

unixarenacfg2

unixarenacfg2 (current)
