It will be great if you could post some of these outputs below. Also do you use LVM on this machine?


#df -h
#fdisk -l
#multipath -v2


Thanks!

Filesystem and storage arrays confusion

Hi Friends, I have a host(SuSe Linux 10.4) which has 2 luns presented from 2 different arrays HP eva and xp. we are planning to migrate hp eva to 3par. When i look for physical volume i see /dev/dm-4, /dev/dm-5, /dev/dm-7and when i look for multipath -ll i see dm-8,dm-9,dm-7. So i can't confirm... (1 Reply)

NAME
pvcreate - initialize a disk or partition for use by LVM SYNOPSIS
pvcreate [-d|--debug] [-f[f]|--force [--force]] [-y|--yes] [-h|--help] [-v|--verbose] [-V|--version] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvcreate initializes PhysicalVolume for later use by the Logical Volume Manager (LVM). Each PhysicalVolume can be a disk partition, whole disk, meta device, or loopback file. For DOS disk partitions, the partition id must be set to 0x8e using fdisk(8), cfdisk(8), or a equiva- lent. For whole disk devices only the partition table must be erased, which will effectively destroy all data on that disk. This can be done by zeroing the first sector with: dd if=/dev/zero of=PhysicalVolume bs=512 count=1 Continue with vgcreate(8) to create a new volume group on PhysicalVolume, or vgextend(8) to add PhysicalVolume to an existing volume group. OPTIONS -d, --debug Enables additional debugging output (if compiled with DEBUG). -f, --force Force the creation without any confirmation. You can not recreate (reinitialize) a physical volume belonging to an existing volume group. In an emergency you can override this behaviour with -ff. In no case case can you initialize an active physical volume with this command. -s, --size Overrides the size of the physical volume which is normally retrieved. Useful in rare case where this value is wrong. More useful to fake large physical volumes of up to 2 Terabyes - 1 Kilobyte on smaller devices for testing purposes only where no real access to data in created logical volumes is needed. If you wish to create the supported maximum, use "pvcreate -s 2147483647k PhysicalVolume [PhysicalVolume ...]". All other LVM tools will use this size with the exception of lvmdiskscan(8) -y, --yes Answer yes to all questions. -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about pvcreate's activities. -V, --version Print the version number on standard output and exit successfully. Example Initialize partition #4 on the third SCSI disk and the entire fifth SCSI disk for later use by LVM: pvcreate /dev/sdc4 /dev/sde DIAGNOSTICS
pvcreate returns an exit code of 0 for success or > 0 for error: 1 no physical volume on command line 2 error removing existing lvmtab entry for new physical volume 3 error setting up physical volume structure 4 error writing physical volume structure to disk 5 wrong partition type identifier 6 error physical volume name 7 error getting size of physical volume 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line SEE ALSO
