I have Netapp LUNS mapped to a Centos server. when I run iostat, I see all the individual disks that are mapped. I have three LUNs - for this purpose they are four disk LUNS: Lun1=(sda1, sda2, sda3, sda4), Lun2=(sda5, sda6, sda7, sda8) and Lun3=(sda9, sda10, sda11, sda12). I want to find the wKB_PS and rKB_PS to check the SAN performance. I wrote a search: index=os sourcetype=iostat host=databseservername | multikv | search Device="sda1" |time chart span=1m xax(wKB_PS) max(rKB_PS)
that works great on a single device/drive. How to I do four disk devices in one aggregated LUN?
