I blew away the original VM I was using for testing as it came time to do the things for real in production - and, as much as I hated it, I just added the disk and rebooted the production machine to make it "see" that disk. However, I have then decided to investigate the matter further. So I created a new one. It is running on an ESXi 5.5 server, VM Version 10, VMware Paravirtual SCSI controller, configured for RedHat 6/64-bit OS, running Centos 6/64 bit. And it worked perfectly when it came to "seeing" a hotplugged disk drive. So I am not sure what to make of all of it - but it looks like freshly created VM's are OK and it was indeed something to do with the VM settings.

Re: [CentOS] getting a CentOS6 VM on VMware ESXi platform to recognize a new disk device
Hello Julius, Thanks - but it doesn't seem to work. I installed sg3_utils and ran #scsi-rescan but that seemed to have done nothing for some reason. Cheers, Boris.

Hi Boris, Just rescan the scsi host. #scsi-rescan #if you have sg3_utils package #lsscsi Or #echo "- - -" > /sys/class/scsi_host/host[n]/scan Julius > On Nov 4, 2015, at 15:31, Boris Epstein wrote: > > Hello all, > > Is there a way to recognize a hot-plugged disk (i.e., to get the system to > recognize it and build the appropriate /dev/sd* device for the new device) > without a reboot? > > Thanks. > > Boris. > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] getting a CentOS6 VM on VMware ESXi platform to recognize a new disk device
Hello all, Is there a way to recognize a hot-plugged disk (i.e., to get the system to recognize it and build the appropriate /dev/sd* device for the new device) without a reboot? Thanks. Boris. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
