0x0000200c uint32_t id2; 0x4c0d30d2 Time = Mon Jun 7 11:48:02 2010

i.e. pvcreate(1m) was run on CPU with ID 1094386684 at Mon Jun 7 11:48:02 2010

0x00002010 uint32_t id1; 0x413b03fc CPU ID = 1094386684

0x00002014 uint32_t id2; 0x4c0d30d3 Time = Mon Jun 7 11:48:03 2010

i.e. vgcreate(1m) was run on CPU with ID 1094386684 at Mon Jun 7 11:48:03 2010

Since the lvm tool lvmmeta may not always be available you can also read out PV-ID

and VG-ID using standard commands that are available on any HP-UX system.

 How to use xd(1) to extract PV-ID and VG-ID:

# xd -j8200 -N16 -tu /dev/rdisk/disk3_p2

0000000 1094386684 1275932882 1094386684 1275932883

PV CPU-ID PV timestamp VG CPU-ID VG timestamp

The above information translates to:

 pvcreate and vgcreate was run on the sytem with systemID (uname –i)

1094386684

 pvcreate was run at timestamp 1275932882 (seconds after Jan 1

1970 0:00

UTC)



 vgcreate was run at timestamp 1275932883 (1 second later)
