Hi,

I'm building two nodes(active and standby) HACMP environment when strange thing happens as belows:

there's two shared disks: hdisk2 and hdisk3, upon which I build datavg1 and datavg2 as shared VG seperately using cluster LVM, but I find that both node1 and node2 are able to vary on the two shared non-concurrent VG at same time whether or not HACMP is running, and I don't know why and how to resolve this problem, so please help, any clue would be appreciated, thanks.

check your reserve_lock:

lsattr -El disk#

reserve_lock yes Reserve device on open True

This is what allows you to mount a vg concurrently on two systems, regardless of if you are using a supported solution like gpfs current HA. AIX can really let you shoot yourself in the foot sometimes.
