what help are you looking for?

This can happen, and is not really a huge issue. Fixing it usually requires either moving back the remote chunk to the right place or a tune of the LD's such that the data is moved to a newly created LD. Both can be done online.

I'd advice you to contact HP support to have your system checked out though, so nothing is overlooked and they can help you as well on properly re-mediating it.

I understand, that this is not critical situation. But I can't update InServ to the latest version - because I have this error.
How I can determine which chunklets should be moved?

sorry for the slow response. simplest answer call HP support and let them help you.

if you do it yourself, you'll first need to know what chunks are actually remote, and if you can safely move them back to the original spot without degrading (cage) availability.

this is a simple script for an environment with management tools under linux, to check that and write the checks to a file:

Code:
touch remotechunks
for chunk in $(checkupgrade | grep tp | awk '{print $3":"$4}'); do movech –dr -perm -f $chunk >> remotechunks;done


if you are a windows box, you'll have to rewrite this to something that works with DOS.
Richard might be able to help you with that. should be a similar easy oneliner.

fyi: i've tested this on a system with 3.1.2 MU1, and MU2, no idea if it works on other firmware, but the outputfile should tell us that.

post the output here, and we'll be able to say if it is possible to move them safely.

I have 3PAR CLI on Linux box. Can you explain, how and where I should run your script?
sorry for stupid questions.
