aplicc

Hi,

If I have 2 groups running on an vcs node,how could I find out what processes belong to group A and what processes belong to group B?Maybe if I look at user and group of every process,and this should to meet the user and group when I issue ls -l /dir/application?

>>> This needs manual mapping, there will be no such flag which will indicate whether a process belongs to group A or B. If the application is started with specific user credientials then yes you can but this also may be confusing. For e.g if both service group contains Oracle DB, both may use Oracle user name to start so you won't be able to identify with username, rather in this example of DBs, instance name can be an identifier..

I like to control every step in recovery of an volume with 2 plexes on stale.
Based on size and flag I will select the plex I wish to recover first.right?Then with vxrecover I start the volume with this plex.Then I ask to the user who uses this volume to check if all the files are in place.If yes,then I recover the second plex.During this recovering the user could work safely.right?

>> Not based on size, but should be based on structure of volume. If its a mirrored volume & if both the plexes were active, you can choose to recover any plex first. If it was a mirrored volume & 1 plex was already down (that means it doesn't have all the updates) & then you hit second plex down as well (which had updated data), then you would want to recover later plex as it had updated data.

Then I ask to the user who uses this volume to check if all the files are in place.If yes,then I recover the second plex.During this recovering the user could work safely.right?

>> Correct

Hi,

You state:

If it was a mirrored volume & 1 plex was already down (that means it doesn't have all the updates) & then you hit second plex down as well (which had updated data), then you would want to recover later plex as it had updated data.

You say that in this case i should to offline also the 2nd plex(with good data),so now the 2 plexes are offline.right?then vxrecover plex_with_gooddata?right?

then ask the user to verify the files.

But what about the case when i recover first plex,and user says that files are missing,then i recover the 2nd plex and the same from this user.should i use the restoration from backup?

thanks so much.
