Clariion Consistency Group name - length limitations bug - See here for info

[steve31783]

Test failover ran fine.. actual failover "failover of luns failed"..

Noticed in the logs that the name of the CG assigned seems to be cutoff...

[003828]10/05 10:48:10 327Failover.cpp @000070 PromoteConsistancyGroups CG_for_LUN235_VM_SATA_30B_Mirro(Array:APM000) normal promote failed. Error Details: The Mirror Group name specified cannot be found

[003828]10/05 10:48:10 327Failover.cpp @000075 PromoteConsistancyGroups Waiting for 50734 ms before another normal promote

[003828]10/05 10:49:01 063Failover.cpp @000077 PromoteConsistancyGroups Trying another normal promote for Consistancy Group CG_for_LUN235_VM_SATA_30B_Mirro

Is this a function of logging, or is there a maximum # of characters for the name of the CG?

Making the name much smaller fixed the issue.. woohoo!

If anyone knows the actual limit, that would be great.

I followed up with our vmware rep who contacted EMC.

Clariion has a limit of 32 characters for the CG names, however the solutions enabler API trims the last two characters from the name. A bug report has been filed with the EMC API team to address the issue, and the current work around is to trim your CG names to 30 characters or less.

An EMC KB article and possibly a vmware one as well) will soon be released regarding this, and EMC will have the fix ready in the upcoming release of solutions enabler.

Hopefully this info. will help someone out there. Thanks.
