The Host Side Linking Pattern for Linux is designed to scan a host in order to establish relationships between:
First, the pattern identifies the different drives and connected storage volumes. It then creates corresponding disk drive nodes in the BMC Discovery environment.
The Host Side Linking Pattern for Linux creates or triggers the following relationships:
The Host Side Linking Pattern for Linux launches commands that may require specific execution privileges. The pattern first run commands as the normal user that discovery is using. In case of failure, commands are rerun using PRIV_RUNCMD. In that case, PRIV_RUNCMD will need to be configured to use an appropriate privilege elevation mechanism.
The list of commands that may require privileged rights is:
* The pattern may stop if one of these key commands is unable to run successfully.
The Host Side Linking Pattern for Linux reports hardware RAID devices as a single disk, i.e, if the host contains disks or disk enclosures connected with a hardware RAID controller, the pattern will only show the logical disks exposed by the controller.
Disk scanning is skipped at the following conditions:
