networker 8.1 parallel save streams (pss) on unix with "virtual client" ???
Hi,
I wonder whether anyone out there also ran into this, and has a workaround.
The user has partitioned UNIX boxes (IBM POWER servers with LPARs), that (according to Networker licensing rules) are covered by Virtual Edition Client (VEC) licenses. This needs a setting of the client resource: "virtual client"=yes. Otherwise these partitions/LPARs are backed up just as like any other normal clients: LAN-based, with Networker client software installed in the LPAR.
With a recent upgrade to 8.1 (SP1) we try to utilize the new feature of parallel save streams (PSS) for these UNIX systems. (The background: the data to be backed up are layed out in a non-optimum way of having a very large amount of data in one single directory, so traditional and simple ways of multiplexing are not possible. PSS could help a lot here.)
But the problem is: when we want to configure those clients for PSS (param in client resource: "parallel save streams per save set"=yes, under globals 1 of 2), we get the following error message:
"parallel save streams per save set and virtual client are not allowed together"
so we
- either use PSS, but then we have to disable the "virtual client" setting and then have to forget the VEC licensing (and allocate client connection CC licenses for those partitions/LPARs)
- or stay with the VEC licensing, but then we can not utilize the new and sought-after feature of PSS.
Any experience, idea, or workaround for this?
Thanks.
Regards,
Geza

By default it is not allowed to use PSS on virtual clients and I suspect engineering didn't thought of zones, LPARs, VPARs and similar, but rather classic x86 hypervisors when they introduced this limit. Since you have opportunity to se which client is virtual on your own, you can be honest cheater and promote one (or as many LPARs you have) physical client to virtual and fake his physical host to be one of existing one to save license and place LPARs to be physical. I'm not sure if this has been reported to EMC, but unless you open a ticket it won't change so I would suggest to open a ticket. Sometimes, you get surprised and discover there is already modified binary which may have certain feature working differently as it has been requested already by others.
