Probably should've known this. Linux commands lparstat, lscpu, lsblk

Body

In the category of learning something new on a regular basis, over the last week I discovered some commands on Linux running on Power systems which were new to me.      Turns out "lparstat" has been implemented, and a colleague here in the LTC pointed out two commands "lscpu" and "lsblk" which I hadn't seen before.

Trying these out on a system with POWER7, 

# cat /etc/*release*
SUSE Linux Enterprise Server 11 (ppc64)
VERSION = 11
PATCHLEVEL = 2

# rpm -qf `which lscpu`
util-linux-2.19.1-6.29.3

# rpm -qf `which lsblk`
util-linux-2.19.1-6.29.3

# rpm -qf `which lparstat`
powerpc-utils-1.2.11-0.4.2.1

For lparstat, there is a utilization view and an informational view of the LPAR.

# lparstat

lscpu is available, although the socket calculation isn't correct in the realm of terminology that we more typically use on POWER systems.    I'll need to follow-up on that, in our thinking the two nodes are sockets, and these processors are 8-cores per socket.

# lscpu

lsblk is available.   It provides another view of the block devices on a system.
