showing multiple disks for single LUN

Dear Team,

 

I assigned a LUN from MSA P2000 to HPUX rx2800 servers in 2 node cluster to FC0 and FC1 port of both servers.

after scanning i did "ls -ltr /dev/rdisk" where it showing 4 new disks, which one should i use for LVM.

 

Regards,

Majhar Mujawar

Since rx2800 runs 11.31 multipath is built-in.

Use the agile device file (/dev/disk/diskxxx) for LVM, each LUN has only 1.

# ioscan -fNCdisk

# ioscan -m dsf


Hope this helps!
Regards
Torsten.
