OK, so I had a NIM master with two network interfaces, en0 and en1. The en0 interface was connected to the 192.168.10.0 network and the en1 interface was   connected to the 10.1.1.0 network. When the master was initially configured, we chose en0 as the primary install interface. The master could now install NIM clients on the 192.168.10.0 network, without any additional NIM network configuration.   root@nim1 / # ifconfig –a en0:... [More]

If you have the AIX iSCSI Software Initiator (iscsi0) configured on your system, you may find that nmon reports some “funny” information under the Disk Adapter (a) and Disk I/O (d) screens, such as:   ┌─topas_nmon──4=Top-by-RAM-use───Host=aix1 Refresh=2 secs───15:09.41──────────────────────────┐ │ Disk-Adapter-I/O ─────────────────────────────────────────────────────────────────────────────────────│ │Name          %busy     read    write        xfers Disks Adapter-Type                                  │ │vscsi1          0.0     ...

Need to update the running attributes of a virtual SCSI adapter on an AIX system? Try these steps.   I want to change value for the   vscsi_err_recov attribute to fast_fail . I can’t do this if the adapter is busy i.e. has open/available paths to a disk device.   # lsattr -El vscsi2 vscsi_err_recov delayed_fail N/A                       True vscsi_path_to   0            Virtual SCSI Path Timeout True   # chdev -l vscsi2 -a vscsi_err_recov=fast_fail Method error (/usr/lib/methods/chggen):         0514-029 Cannot perform the requested...

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. But when that’s not been used, what are the options?   The ps command will only help if we bind a process to a specific CPU. For example, here we can see that the bootpd process has been bound (and then un-bound) on processor 3:   # bindprocessor -q The available processors are:  0 1 2 3   # bindprocessor 8585302 3  ...
