Run VIOS command from the HMC terminal (hacking the VIOS from HMC)

If ,for whatever reason, you can`t get access to your VIOS because the Desktop that you are using in different VLAN and dose not has access to the VIOS OR you don`t have the VIOS server Username and Password! 

Well,You don`t have to worry about that ;-) 

First of All,We need to run couple of commands to get the following info:
1)the name of the managed system
2)the ID of the VIOS LPAR

To get the name of the managed system:
hscroot@hmc:~> lssys -r sys -F name
 amer-power795

Where amer-power795 id the name of the managed system.

To get the the LPAR ID of the VIOS:
hscroot@hmc:~> lssys -r lpar -m amer-power795 -F name,lpar_id
VIOS,1
amer,2 

Where VIOS and amer are the name of the LPARs on the managed system amer-power795


I could tell you that you are ready to start hacking and diving into your VIOS server without the need to user name and password.

hscroot@hmc:~> viosvrcmd -m amer-power795 --id 1 -c "The VIOS Command"

Examples 
--------   

-To check the SCSI mapping,run:
hscroot@hmc:~> viosvrcmd -m Power720.2-8202-E4B-SN06CDA0P --id 1 -c "lsmap -all" 


-To check all the adapters,run:
hscroot@plazahmc:~> viosvrcmd -m Power720.2-8202-E4B-SN06CDA0P --id 1 -c "lsdev -type adapter"

-To check the Virtual adapters:
hscroot@plazahmc:~> viosvrcmd -m Power720.2-8202-E4B-SN06CDA0P --id 1 -c "lsdev -type adapter -virtual -field name status"



Hope you like this tricky and geeky piece of info!  :)
