nvme-stas Mr Martin Belanger Dell, Inc. stasadm 1 stasadm STorage Appliance Services admin functions stasadm OPTIONS COMMAND OPTIONS stasadm is used to configure nvme-stas. The configuration is saved to /etc/stas/sys.conf. Although nvme-stas' configuration is saved to /etc/stas/sys.conf, it's still possible to interoperate with the configuration of nvme-cli and libnvme. nvme-stas allows one to save individual parameters such as the Host NQN and ID outside of /etc/stas/sys.conf. This allows, for example, using the same default Host NQN and ID defined by nvme-cli and libnvme in /etc/nvme/hostnqn and /etc/nvme/hostid respectively. To tell nvme-stas that you want to use the those files, simply use stasadm's --file=FILE option. The following commands are understood: hostnqn Generate the Host NQN. This is typically used as a post installation step to generate /etc/nvme/hostnqn. The NVMe base specifications says: An NQN is permanent for the lifetime of the host. For this reason, the host NQN should only be generated if /etc/nvme/hostnqn does not exist already. hostid Generate the Host ID. This is typically used as a post installation step to generate /etc/nvme/hostid. Although not explicitly specified in the NVMe specifications, the Host ID, like the Host NQN, should be permanent for the lifetime of the host. Only generate the Host ID if /etc/nvme/hostid does not exist. set-symname [SYMNAME] Set the host symbolic name. The symbolic name is an optional parameter that can be used for explicit registration with a discovery controller. clear-symname Clear the host symbolic name. The following options are understood: -fFILE --file=FILE By default, hostnqn and hostid save the values to /etc/stas/sys.conf. This option allows saving to a separate file. Traditionally, nvme-cli and libnvme retrieve the default Host NQN and ID from /etc/nvme/hostnqn and /etc/nvme/hostid respectively. The --file=FILE option can be used to tell nvme-stas that it should use those same configuration files. On success, 0 is returned; otherwise, a non-zero failure code is returned. $ stasadm hostnqn --file /etc/nvme/hostnqn $ stasadm hostid -f /etc/nvme/hostid $ stasadm set-symname LukeSkywalker nvme-stas 7
