Scalable volume groups first appeared in AIX 5.3. They allow a maximum of 1024 physical volumes and 4096 logical volumes per volume group. This is pretty cool for large systems. In the ‘old days’ we could end up in situations where we’d reached the maximum PV count (32 or 128) for a VG and have to create a new VG to work around the issue.   I use scalable VGs for all my new large AIX system builds.   The following command will create a scalable VG (named svg ) on hdisk4. You’ll notice that MAX PVs is set to 1024 and MAX LVs is set to 256.... [More]

There are two new HMC (V7.7.3.0) commands that can force a client Virtual Fibre Channel adapter to log into a SAN. This should make the life of the AIX and SAN administrator easier, as they will no longer need to install AIX in order for the new VFC adapters to log into the SAN. Although there was an unsupported method* for doing this already (see links below). Nor will the SAN admins need to “blind” zone the WWPNs.   There was some indication of this in the latest VIOS FP readme:  ... [More]

A question I received this week from a customer.   Hi Chris,   Is there  a way to find on which processor a process is executing?   If I’ve used binprocessor, ps –emo THREAD, would show which processor a process is bound too.
