Hyperscale x does not detect Sandisk automatically

i*m using Hyperscale x nodes that are also Vsaproxys
when adding a new Fcdisk to the node it will not be discoverd automatically.

Is there an option to let discover the Hyperscale node the SAN Disk.

Hi Chr…

HS-X is build on Linux OS, therefore you need to rescan the scsibus to discover/create new devices.

automatic scan is only done during reboot or when mapping a new target, but not a new LUN.

try something like :

scan-scsi-bus.sh -r -f -m -w –hosts=$(cd /sys/class/fc_host;ls -xd *|sed -e ‘s/ /,/g’)

this re-scans the targets connect to FC Hosts only.
If you map LUNs with very high LUN IDs, you might also need to modify the 
/etc/default/grub and for LUN support of up to 4096 LUNS, add scsi_mod.max_luns=4096 to the GRUB_CMDLINE_LINUX parameter

I also created a workflow, that daily runs this scsi-scan on all HS-X Nodes to update the SCSI configuration, in case new LUNs have been introduced.
