# useradd rhel; su - rhel Obtain PKEY, delete the third digit of PKEY, and use this value to replace {pkey} in 4.d. # cat /sys/class/infiniband/mlx5_0/ports/1/pkeys/* | grep -v 0000 | head -n1 For example, if the obtained PKEY is 0x8f05, delete the third digit to obtain 0xf05.
Do not modify or delete files in the /usr/local/.hpccluster directory. Otherwise, the cluster may encounter errors. The authorized_keys file in the /usr/local/.hpccluster/role/.ssh/ directory is used only for system maintenance.
Node management Query, start, stop, restart, and delete nodes in HPC-S² clusters. Shared storage management Provide storage for HPC-S² clusters by using Scalable File Service (SFS).
