Which NetApp feature presents LUNs only within the HA pair?
Selective LUN Mapping (SLM) is the feature that presents LUNs only within the HA pair. SLM allows administrators to control which LUNs are visible to which hosts, ensuring that LUNs are only accessible through the designated HA pair, thus improving security and manageability.
For more information, see:
NetApp Documentation on Selective LUN Mapping
NetApp Community on LUN Mapping
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to support multiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.
For more information, refer to:
NetApp Documentation on SVM Configuration
NetApp SVM Best Practices
What is the maximum size for a LUN in NetApp ONTAP 9.14.1 software?
In NetApp ONTAP 9.14.1 software, the maximum size for a LUN is 128TiB. This limit ensures that large datasets can be stored and managed efficiently within a single LUN, catering to the needs of high-capacity SAN environments
An administrator finishes an installation of a new NetApp ASA system at the customer site and creates a new LUN. The customer wants to restrict the access of the LUN to specific UFs.
Where would the administrator configure this?
To restrict access to a newly created LUN to specific hosts, the administrator should configure the igroup (initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs. This ensures that only authorized hosts can access the storage, enhancing security and access control.
For more details, refer to:
NetApp Documentation on iGroups (NetApp).
A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
NetApp Documentation on iSCSI Configuration (NetApp).
