Inconsistency in the device partitions listed under "/proc/partitions" file and "fdisk -l" output
Issue
- can not read from a disk path
- can not read from a partitions created on multipath device (otherwise I can do it on all other veritas disks) :
root@calypso:[/root]# dd if=/dev/sdbcx3 of=/dev/null count=20
dd: opening `/dev/sdbcx3': No such file or directory
root@calypso:[/root]# dd if=/dev/sdbyg3 of=/dev/null count=20
dd: opening `/dev/sdbyg3': No such file or directory
- why do we have difference between fdisk and /proc/partitions output ? fdisk show both partitions but /proc/partitions file does not show both the partitions.
- why do not we have partition 3 for scsi disk inside /proc/partitions ?
Environment
- Red Hat Enterprise Linux (RHEL) 5 U4
- Veritas multipath (DMP)
