Hi Raj

The daily checklist for MC/Serviceguard is like below

1. Check cmviewcl or cmviewcl -v in all cluster nodes.
2. Check the cluster VG to apply command vgdisplay -v|more
3. Check pkg log.

Re: Day to Day System Admin activities on Serviceguard

Once cluster is setup and running fine, it does not require any manual intervention on daily basis.

If there is any issue then only a system administrator's intervention is required at that time. However the things mentioned above by ahsan is for monitoring purpose only, we can not consider that as a system admin task.

So I don't think there is any activity required on service guard on daily basis, until unless u have some testing or scheduled maintenance.

However u should be aware of switching package manually from one node to another one, in case if it is not switching to the configured node after failing on primary node. Like this you could check the cluster lock disk health since that plays major role in cases of tie breaker if it is a 2/3/4 node cluster. Like this there are few things which u should be familiar with so u could handle these kind of issues effectively.

I hope this is what you wanted to know.

HI Raj

You can email the status of cmviewcl -v to your inbox daily basis and all mounted file systems etc. you can make script as health check
if you find package is moved to secondary server then your intervention is required, you have to find the root cause why they package is moved etc

You are not assigning the points for our suggestion it is more important

Hi,
cmviewcl is enough.
you can write some script which one can generate mail to you or when the cluster failover to its second node it can send you sms.

Thanks & Regards

Shalom,

None.

You should write a small cron job to check the status of critical packages and have it email an admin if something is wrong.

There is absolutely nothing that you need to do on a day to day basis.
