CREATING FILE SYSTEM ON DISK PROVIDED FROM VIO

CREATING FILE SYSTEM ON DISK PROVIDED FROM VIO

THIS DOCUMENT WILL GIVE YOU STEP BY STEP TO PROVIDE  DISK TO LPAR USING VIRTUAL SCSI IN A MPIO ENV FOR MORE DETAILS VISIT http://aix-administration.blogspot.com/2011/01/in-depth-of-disk-assignment-from-vio-to.html

As a administrator we need to go into concepts of activities performed by us , i am assuming that the reader does not knows much about the vio server and client and will start from the scratch ,
  
AT THE CLIENT SIDE  GET THE LPAR NAME AND LPAR ID

If we know lpar id we can identify this lpat on hmc and vio server side


#uname -L


NOW WE WILL PERFORM OPERATION ON THE LPAR WHICH WE GOT FROM THE ABOVE COMMAND

But how do we know which managed system to go its quiet simple run command uname -a and it will give you the serial number , most of the times managed system name has serial number in their names
If you still cannot come to a answer iew my post http://aix-administration.blogspot.com/2011/01/in-depth-of-disk-assignment-from-vio-to.html

IN HMC OPEN THE MANAGE SYSTEM

CHECK PROPERTIES OF LPAR 


SELECT THE LPAR AND SELECT PROPERTES FROM TASKS OPTION

THE CLIENT ADAPTER ID AND RELATIVE SERVER ADAPTER AND THE VIO SERVER PROVIDING THAT SERVER ADAPTER IS SHOWN IN THE PROPERTIES AS IN FIGURE FOR EXAMPLE CLIENT ADAPTER ID 4 IS CONNECTED TO SCSI ADAPTER WHONE ID IS 81 AND THE VIO SERVER WHO IS PROVIDING THE SERVER ADAPTER IS MENTIONED

IF YOU SEE RUN lscfg -vl <adapter name> YOW WILL GET CLIENT ADAPTER ID 

NOW GO TO THE VIO PARTITION WHICH IS SHOWN IN THE ABOVE FIGURE AND SEE ITS VIRTUAL ADAPTERS BY GOING IN THE PROPERTIES OF THE VIO SERVER

THE ABOVE FIGURE SHOWS THAT THE SERVER ADAPTER WITH ID 81 IS PROVIDING ITS RESOURCES TO CLIENT ADAPTER WITH ID 4

NOW LOG ON TO VIO SERVER AND
SEE ALL DISKS AVAILABLE


BY USING

lsdev -type disk

OR

VERIFY THEDISK AVAILABLE ON VIO SERVER

#lsdev |grep hdisk

CHECK THE VHOST ADAPTER ASSOCIATED WITH THE LPAR ID

WE CAN ALSO USE COMMAND

lsmap -all |grep vhosts

THE LAST COLOUMN OF THE ABOBE COMMAND WILL SHOW THE LPAR ID

ASSIGN DISK TO VHOST ADAPTER

#mkvdev –vadapter  vhost23 –vdev hdisk113 –dev eebackupvgpv

ON CLIENT LPAR CHECK FOR NEW DISK AND PATHS FROM THE WHICH THE DISK IS COMING

ASSIGN THE DISK  FROM OTHER VIO ALSO

CHECK FOR DISK ATTRIBUTES ON VIO SERVERS

NOW THE FILE SYSTEM ON CLIENT CAN BE CREATED

CHECK FOR THE DUAL PATH PROVIDED FROM OTHER VIO ALSO
