Hi Hari, Though there is root account in VNXe, it should be only used by EMC support personnel. The Linux OS running on the SPs is a customized version and has lot of proprietary services running. Running any inadvertant commands may result in SP crash or data loss. For this reason, only trained professionals are allowed to use root access.  All administrative functions can be done using admin account through GUI or Unisphere CLI. The SSH access is limited for support purposes only.
I am currently working on VNXe with admin and service accounts.  Do VNXe have root account? if yes could you suggest me default password or directions for reset the root password.  Thanks, Hari
