Subject: Fun with Device Locations

Here are a few commands to locate physical devices. These commands are useful in a partitioned environment where locations are virtual.

• lsdev -Cc adapter -s pci - list all adapter slots
• lsdev -p adapter - lists devices owned by an adapter
• lsdev -Cl adapter -F parent lists the parent adapter for a device (like a disk drive)
• lsdev -Cl adapter - virtual device location (for LPARs)
• lscfg -vl adapter - actual device location

So, for example, to locate the physical adapter connected to hdisk0:

• # Identify the parent adapter
  lsdev -Cl hdisk0 -F parent
• # Locate the parent adapter
  lscfg -vl parent
