Hi All,

I have MC service gaurd installed in my HP-UX server.And i am new in Clustering.

When i running the following command
pairdisplay -g vgdata1(vgname) command it gives me the following output.

and when i have run this command in my other HP-UX server it gives me the following output.

So what is it mean in first output it shows PSUS ASYNC
SSUS ASYNC
in second command it shows
PAIR ASYNC
PAIR ASYNC

what is the meaning of both the output

Hi Sumit,

Let me first clear that pairdisplay is not MCSG command, however it is RAID Managers command for XP. Now in RAID Manager for XP you have Primary Volume referred as PVOL and seconday Volume referred as SVOL.

So when both volumes (PVOL & SVOL) are in PAIR then pairdisplay will show the status as PAIR. However when they are in suspended/Split status it will show you the status as PSUS/SSUS. So SUS stands for suspended.

Suspended doesn't mean that mirror is broken it is just splitted and when u resync them only the changes from the last time split will be synced.

You will find lots of documents on docs.hp.com about RAID Manager XP.

Hi,
PSUS and SSUS in P-VOL and S-VOL means that both the volume are in split mode now.

And PAIR P-VOL and S-VOL means that both the volume are in PAIR Mode now.
TO make it full sync with the P-VOl and S-VOl it will takes some time and when the % is showing 99 or 100 that time its full paired.

Thanks & Regards
