Re: HPE 3PAR Storage CMP leaks

Basically it's a leak in CMPs.  I would suggest you just install the patch before your system crashes.

Any documentation in the patch?

Hello Dennis, 

Thanks for replying. I am not a customer but I am new to HPE and have come across this term and wanted to know a layman understanding of this term.

Thanks,

Gigen

Re: HPE 3PAR Storage CMP leaks

The data cache is composed of CMPs.  They are used to cache the data before reading/writing to PDs.

They are also used to transfer info from one node to another.

If you have a leak, this memory becomes lost and if enough, there is no memory to do I/Os, etc.
