I am setting multipathing in vmware workstation & added additional storage disk as storage array, I had configured multipathing in rhel5 but unable to create multipath & getting error as,
[root@server ~]# multipath -v2
/sbin/scsi_id exitted with 1
error calling out /sbin/scsi_id -g -u -s /block/sdb
/sbin/scsi_id exitted with 1
error calling out /sbin/scsi_id -g -u -s /block/sdb
Also checked the logs as,

it seems like you have mis-configured something into multipath config file, see the output of scsi_id.
scsi_id is the command which is used to find the SCSI-ID from scsi disk drive and argument which is supplied to is "/block/sdb" which is never exists on rhel5.
all the device's are stored into "/dev" directory.
if you check the multipath.conf file there should be line where you have mentioned this
Code:
/sbin/scsi_id -g -u -s /block/sdb
it is deprecated or will not work on, not even on redhat but many more. so you need to change it something like this.
