How do I add a spare disk to aggregate netapp?
The storage aggregate add-disks command adds disks to an existing aggregate. You must specify the number of disks or provide a list of disks to be added. If you specify the number of disks without providing a list of disks, the system selects the disks.
How do I add disk shelves to netapp?
For disk shelves, you insert a SAS cable connector with the pull tab oriented up (on the topside of the connector).
- Install the disk shelf, power it on, and set the shelf ID.
- Disconnect the SAS cable from the IOM B port of the last shelf in the stack, and then reconnect it to the same port in the new shelf.
What is a disk aggregate?
An aggregate is a collection of disks (or partitions) arranged into one or more RAID groups. It is the most basic storage object within ONTAP and is required to allow for the provisioning of space for connected hosts.
What is netapp aggregate volume?
The aggregate provides storage, based on its configuration, to its associated FlexVol volumes or Infinite Volume. Aggregates have the following characteristics: They can be composed of disks or array LUNs. They can be in 64-bit or 32-bit format.
What is a NetApp node?
NetApp HCI storage nodes are hardware that provide the storage resources for a NetApp HCI system. Drives in the node contain block and metadata space for data storage and data management. Each node contains a factory image of NetApp Element software.
What is Vserver in NetApp?
A virtual storage server (Vserver) contains data volumes and one or more LIFs through which it serves data to the clients. Starting with clustered Data ONTAP 8.1. 1, a Vserver can either contain one or more FlexVol volumes, or a single Infinite Volume.
What is difference between LUN and volume?
A LUN is a logical volume from the point of view of the storage. From the client point of view the LUN it is a disc volume that can be partitioned. Volume is a generic term. It means a contiguous storage area.
What are the types of volumes in NetApp?
Data ONTAP provides two types of volumes: FlexVol volumes and Infinite Volumes. There are also volume variations, such as FlexClone volumes, FlexCache volumes, data protection mirrors, and load-sharing mirrors. Not all volume variations are supported for both types of volumes.
What is NetApp cluster mode?
A cluster consists of one or more nodes grouped together as (HA pairs) to form a scalable cluster. Creating a cluster enables the nodes to pool their resources and distribute work across the cluster, while presenting administrators with a single entity to manage.
What is a LIF in NetApp?
A LIF (logical interface) is an IP address with associated characteristics, such as a role, a home port, a home node, a routing group, a list of ports to fail over to, and a firewall policy. You can configure LIFs on ports over which the cluster sends and receives communications over the network.
What is RAID DP in NetApp?
RAID-DP is a standard Data ONTAP feature that protects your data from double-disk failures or single-disk failures with media errors. This feature significantly increases the fault tolerance of RAID groups in Data ONTAP over traditional single-parity RAID.
How to use the storage aggregate add-disks command?
The storage aggregate add-disks command adds disks to an existing aggregate. You must specify the number of disks or provide a list of disks to be added. If you specify the number of disks without providing a list of disks, the system selects the disks. This parameter specifies the aggregate to which disks are to be added.
How do I add a spare disk to aggr0?
The command I gave you will add the spare disk to aggr0. Creating a new aggregate would be aggr create -d .. 2013-04-01 01:28 PM Okay, so this shows what you initially described – 6 drives, one aggregate with 3 data + 2 parity, and one spare.
How does Data ONTAP add disks to a raid group?
If new is specified, the disks are added to a new RAID group, even if the disks would fit into an existing RAID group. If all is specified, the disks are added to existing RAID groups until all existing RAID groups are full. Then Data ONTAP creates one or more new RAID groups and adds the remaining disks to the new groups.
What is an aggregate in a raid group?
An aggregate might include a mix of different RAID types. The following example adds 10 disks to an aggregate named aggr0. The disks are added to a RAID group named rg1: In this example, an aggregate is converted to a Flash Pool aggregate using SSD capacity from a storage pool.
