In my previous article, I showed how you can use nmon in VIOS to display the performance statistics of hdisks that are mapped to client LPARs. This is achieved by creating a file which nmon reads and then displays the relevant performance data. The script I used required that the virtual target devices (VTDs) mapped […]
Masterclass: how to monitor VIOS vSCSI disk performance
In my previous article I showed how you can use nmon in VIOS to display the performance statistics of hdisks that are mapped to client LPARs. This is achieved by creating a file which nmon reads and then displays the relevant performance data. Let’s look at a script I created to automatically generate the file […]
How to monitor client LPAR vSCSI disks in VIOS
Many customers use vSCSI disk-mapping in VIOS to present external storage volumes to their client LPARs. There are proponents of vSCSI, NPIV and Shared Storage Pools. These all work very well. I find that AIX-minded technicians will lean towards NPIV because that’s what they have used traditionally. IBM i technicians will tend to use vSCSI […]
