I'm having a little issue. I've a live system which run on RHEL 6.7 (VM) and have VMware 6.5 (which is not managed by our group) . The issue is, the other group tried to extend the capacity of an existing disk on a VM. After that, I ran a scan command to detect new disk as usual with
echo "- - -" > /sys/class/scsi_host/host0/scan, but nothing happened. They added 40G on sdb disk which should be 100G and I saw that is changed on VM but not in Linux. So where is the problem ? As I said, this is a live system, so I don't want to reboot it.
Here is the system :
