We can use below commands to see the lun status from Esxi Host
. Please ssh to the Host and execute the command replace “eui.a35390c4baa8698f6c9ce900179b8b4c” with the Lun
which you want check .
1.
CLI what a given datastore’s working
path(canonical name) and SATP/PSP plugins, the following command would do:
esxcli storage nmp device list | grep -A 7
eui.a35390c4baa8698f6c9ce900179b8b4c
2. How
to find SCSI reservation conflict ,Lun Read and Lun write status . Please
see the Failed read and Write operation values.
esxcli storage core device stats get | grep –A
14 eui.a35390c4baa8698f6c9ce900179b8b4c
3.
find out how many commands/blocks
were read/written for a given path
esxcli storage core path stats get | grep –A 10 eui.a35390c4baa8698f6c9ce900179b8b4c
4.
To get path list and lun number
esxcfg-mpath –l
eui.a35390c4baa8698f6c9ce900179b8b4c
5.
List All the Luns and all
the paths
esxcfg-mpath –b
6. To obtain LUN
multipathing information from the ESXi host command line:
esxcli
storage core path list
7.
To see HBA device status of Vmware host
esxcfg-scsidevs
–a
8.
To view the CPU, Memory, Network , disk , Luns and VM
performance of a Vmware host . Please execute “esxtop” and use each below
switch to change the view .
esxtop
c – CPU
m – memory
n – network
d – disk adapter
(in our example screenshots below, it’ll be vmhba33/37 depending on which one
represents the sw/iscsi adapter)
u – all LUNs
v – VMs virtual
machine disks (VMDKs)
q – quit the top
