Security is initialized differently for
VNX unified/file and VNX for block systems.
VNX unified/file systems will have the following
management accounts factory installed:
root -
This is a VNX for file local account and provides root-level privileges on the
control station.
nasadmin - This is a VNX for file local account and provides administrator
level privileges on the control station.
sysadmin - This is a global system account and provides administrator level
privileges for both VNX for file and VNX for block.
A system account is a special global account that is
needed for internal communication between block and file services. VNX
unified/file systems require at least one system account. You cannot delete
this system account unless another global administrator account or global
security administrator account is available.
VNX Installation Assistant (VIA) is the utility for
initializing VNX unified/file systems. EMC recommends to change the default
password for the three accounts when first initializing a VNX unified/file
system using VIA.
VNX for block systems do not have any default
management accounts. The Unisphere Initialization wizard is the utility used
for initializing VNX for block systems. Security can be initialized on VNX for
block systems in the following ways:
User
can choose to create a global account when initializing the system using
Unisphere Initialization wizard.
User
can create a global account when first logging into Unisphere.
A system account is not created by default on VNX
for block systems because it is not needed; however, adding another VNX
unified/file system to the VNX for block system's local domain would require a
system account and the user will be prompted accordingly to create a system
account.
For all VNX systems (VNX unified/file and VNX for
block), at least one global account is required. This account must have the
"administrator" or "security administrator" role. An LDAP server(s) can be
configured if LDAP authentication is desired, and other global or local
accounts can also be created.
Security functions having to do with configuring
authentication can be performed either from Unisphere or secure CLI.
