Phil, Run fdasd against them to create the partition and use the partition name in the pvcreate command, eg. pvcreate /dev/dasdm1, and in the vgcreate command. Betsie

I'm trying to set up an LVM. I have 3 10MB disks defined at 8001, 8002, 8003; they appear in /proc/dasd/devices as: 8001(ECKD) at ( 94: 48) is dasdm : active at blocksize: 4096, 2520 blocks, 9 MB 8002(ECKD) at ( 94: 52) is dasdn : active at blocksize: 4096, 2520 blocks, 9 MB 8003(ECKD) at ( 94: 56) is dasdo : active at blocksize: 4096, 2520 blocks, 9 MB So far so good. I dasdfmt-ed them, then did a vgscan and a pvcreate /dev/dasdm /dev/dasdn /dev/dasdo. That worked. Now pvscan and vgcreate both whine. pvscan says: pvscan -- reading all physical volumes (this may take a while...) pvscan -- ERROR "pv_read(): read" reading physical volumes vgcreate says: vgcreate -- ERROR "pv_read(): read" reading physical volumes I tried the dd if=/dev/zero of=/dev/dasd[mno] bs=1k count=1 trick, no change. Running pvscan with -d suggests that it's getting all the way to the end of dasdo before whining. It did say: <1> pv_read_all_pv -- device /dev/dasdm NOT used <1> pv_read_all_pv -- device /dev/dasdn NOT used <1> pv_read_all_pv -- device /dev/dasdo NOT used as it handled each of those. I'm not sure why it said that (but then, I'm not sure why it's doing most of what it's doing). I tried mke2fs on the disks as well, trying to Easter Egg it, but still no change. This is Logical Volume Manager 1.0.5(mp-v6) on SLES8. Anyone got any ideas? I get the list digested so direct replies as well as list replies are appreciated, but of course beggars can't be choosers...
