I’m having a little issue. I have 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 on 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 :
