Hi Siva,

you have multiple options ...

1. you can use vxstat utility to find details of IO on vxvm devices ...

2. If you want to know details path wise & if you are using DMP, you can use vxdmpadm iostat to collect statistics of DMP devices

3. You can look for "FirstLook" utility from Symantec which helps collect lot of these statistics & helps Symantec support to analyze the same ..

To answer your last question, to know what device a volume maps to you need to use

# vxprint -htg <diskgroup> <volume>    (this will print details of volume, look for line starting with "sd" to know the disk in use for that volume)

# vxdisk -e list (this command can help to map OS device names with vxvm disk names)

hope this helps

hi Gaurav ,

Thanks for the reply

In Linux when we use iostat i see vxvm devices named in this way.I need to findout to which vxvm disk these devices would be mapped.

Vxprint -ht would not give the device naming in this way "VxVM27000 ". i didnt checked when i am replying so i may be wrong
