Correct - you'll want to focus on IOPs to devices under LVM control.  Collect the SNMP performance data from those four devices under LVM control.  Let us know if that helps!  Karl
Hi all,  I am new to PowerPath on Linux and this forum. I am trying to determine IOPS on a Linux database server and Net-SNMP is reporting back 8 devices from a VNX5300, each "pair" having a letter and a matching one ending in 1.  .1.3.6.1.4.1.2021.13.15.1.1.2.67 = STRING: emcpowerd .1.3.6.1.4.1.2021.13.15.1.1.2.68 = STRING: emcpowerd1 .1.3.6.1.4.1.2021.13.15.1.1.2.69 = STRING: emcpowerg .1.3.6.1.4.1.2021.13.15.1.1.2.70 = STRING: emcpowerg1 .1.3.6.1.4.1.2021.13.15.1.1.2.71 = STRING: emcpowere .1.3.6.1.4.1.2021.13.15.1.1.2.72 = STRING: emcpowere1 .1.3.6.1.4.1.2021.13.15.1.1.2.73 = STRING: emcpowerf .1.3.6.1.4.1.2021.13.15.1.1.2.74 = STRING: emcpowerf1  Each of these has it's own counters and they are not exact but are very close. I wasn't sure if each of these is legit and load balancing is in play or if this is just a by-product of how PowerPath works. I do know fdisk doesn't show any partitions for the devices ending in 1, so that's where I am most confused.  Any help or guidance appreciated.  - Kyle
