How can i determine which PP's are SAN or Non-SAN,if it is SAN then is there any command to check the space.....

Hi ,

The normal prinipal for any san is that

1. you must load drivers in order for the interface to communciate with the san for example if you have fibre cards connected to EMC then you load power path software

2. Once the san can see the server , then the person looking at the san allocates LUNS to the server
Note:- the san may be set up as raid 5 and raid 1+0 , this means the SAN controls where it puts the data , all you do is say allocate 10GB to your server

3. Once you have allocated the LUN to the server you scan for it , this normally runs cfgmgr / depending on what storage you are using and the s/w installed there should be commands there to run it
This should allocate a hdisk to your server
if you do lsdev -Ccdisk

you probably see something like

hdiskx description of disk e..g Powerpath

4. To view the SAN storage , you can run normal lspv
lslv ( i.e. normal LVM commands )
To view the SAN details , you can depending on what software
is installed on the server query the SAN/lun configurations on the server or you have to logon to the console where the SAN is configured to and view it that way

for example : if you have powerpath . you can use powermt
commands to display , paths, status etc.. of disks

if you are using VA Arrays then you install command view software , and use the cvui utility to view LUNS / SAN configs.

5. The NON - SAN disks you'll know when you do lsdev -Ccdisk

the description will determine whether it is a SAN disk or normal disk .

hope this helps
