Re: Removing a STD-BCV relationship

Hi,

I cannot delete this device, 01D7, and by the error message, (earlier in this thread) this is related to the other device which with once formed a BCV pair.

This device is not related to anything else and I really don't see any reason why I couldn't delete it.

Thank you,

Re: Removing a STD-BCV relationship

028F is a BCV ..is strange that it gave you an error message saying that it's copy session source.  You have not cloned/snap this BCV to anything else ?

Hi dynamox,

I tried to create another device group and to force 028F to become a BCV for another device:

A configuration mismatch was detected among members of your META device(s)

The 2 specific devices 01D7 and 028F are nor mapped or masked in any way. They are really 2 standalone devices not implied in any other relationship.

As an answer for a previous note from Booyah:

early in the morning I ran a "symcfg discover" but the 2 well-known devices 01D7 and 028F are as before:

Re: Removing a STD-BCV relationship

mugurs,

what is happening here is there is a mismatch between either the meta count or the number of cylinders of the devices you are trying to pair..

have a look at the symdev show ouptut fro each device and compare the meta count and the number of vylinders.  Aslo check to see if both are striped or concatenated.

Re: Removing a STD-BCV relationship

Hi Paul ... Unfortunatly I don't have a CLI available, thus can't check my own ... But AFAIK symcli should report if the devices are already part of a metavolume ... Looking at his previous post it looks like the volumes aren't bound to metas... And both have same size (18414 cyls "big" cyls)

Re: Removing a STD-BCV relationship

I'm no expert, but...maybe trying so hard to pull apart first, is the problem.  Have you ever played with a Chinese finger puzzle - the more you pull the more you can not break free..

The state on the devices at the beginning of your post showed that there was some kind of force command issues from the beginning, likely while the devices were in a sync'ing state.  Hence the "SpliNoInc" status.

Why not put down the hammer first...and try to put these devices into their own device group and do a Full Establish resync them.  If you can add them to a DG then that tells me they aren't stuck in another one.  And by resync'ing them you clean up any hanging messages.

Now once they are fully in sync then split them...nice and easy like it should.

Then do the process of removing the BCV from the standard...and taking them out the DG....and getting rid of the DG.

Just a thought,

Rita

Re: Removing a STD-BCV relationship

I did not look at the full thread but to some errors that you are getting. I also see that your error has changed now. Earlier you were getting a different error while canceling the STD-BCV pair and now a different error while est it.

When I compare the symdev show of STD and BCV, i dont see mismatch configuration between the two (both looks 2way mir and no meta member). But if you still want to clear the relationship from BCV device, you can create another STD of the same size (2way mir) and establish -full with BCV. This will override the STD information on BCV device and then you can cancel -force the new STD-BCV relation ship.

Check primus emc122345


This can also be done through INLINES if you do not want to do it using CLI.


Thanks,

Saurabh

Re: Removing a STD-BCV relationship

Hi,

I created again the configuration from the begining:

symdg create testdg

symld -g testdg add dev 01D7 DEV000 -sid xxx

symbcv -g testdg -sid 129 associate dev 028F BCV000

symmir -g testdg -full establish DEV000 bcv ld BCV000
