Hello list, At this moment we have 4 LPARs (VM1 to VM4) that share a SFS on VM4. The resource is shared with AVSVM. We can't use ISLINK here. Also we have a few guest VM's in VM3 for our own 'pleasure'. These use an ISLINK to connect to VM4. For more on this, see "Hiding global resources within an ISFC complex" from June 2001. The post refers to these systems as Gerard has setup the current config.
We are planning to move the 4 LPARs to one LPAR with the 4 LPARs as guest in the host. If possible we would like to take advantage of this new config. One of the options would be to move the SFS to the host and let the guests access the SFS running in the host instead of accessing SFS in VM4 through AVSVM. The network connections are still a matter of concern, both TCPIP and VTAM. TCPIP will have to be setup on the host also. VTAM could just be left on VM4 but maybe it would be nice to get it to the host also. What connections would be possible when we move SFS to the host? Basically anything that could speedup the SFS connections would be an option. ISLINK can connect using a CTC (either real or VCTC) but can I use this from host to guest? If so, how do I 'connect' the ISLINK in the host? And also, when we use ISLINK all databases in the guests are available in the host but would such resources also be available in an other guest also? I.e. the production database is available in the test VM because it is a (remote) resource in the host that is exported to all other ISFC complexes. We could use AVSVM but then we need to setup VTAM in the host as well. When I use AVSVM I guess it would not make the connection any faster so then maybe we'll be better off to leave the configuration as it is. Unless we move VTAM to the host anyway, then we could point the connection to the host instead of to an other guest. Would IPGATE be an option? I did try to get it running on some other systems. I could see a resource in the remote VM but I was not successfull in accessing it. If someone would have an example config for this I'd be very happy. Any other ideas I did not consider yet? Thanks, Berry.
