Mounting the ISO file on the nodes
To install NetBackup Flex Scale, you are required to mount the product installer ISO image file on the node and then boot the server from that ISO image.
How you connect the ISO to the node depends on how you manage the server hardware. The most common method is to use hardware vendor's remote management console and mount an ISO using a virtual CDROM device or a USB storage drive. You can copy the ISO on a laptop and then connect the laptop directly to the server node using the dedicated service port. You then launch the remote management console interface from a web browser and then mount the ISO to the node.
A separate mount point for the ISO is required for each node. For example, for a four-node cluster, create four different mount points and attach the ISO separately for each node.
Note:
The process of attaching the ISO to the cluster nodes is impacted if there is poor network connectivity between the download ISO location and the cluster nodes.
For HPE ProLiant DL380 Gen10 servers, you can use the HPE iLO Remote Console administration interface and use the boot menu options to connect the ISO to the node.
Refer to your server hardware vendor's documentation for instructions on how to boot a server node from an ISO image file.
