Once you have configured the ISCSI storage on VMware ESXi, you can start creating new datastore using those ISCSI LUNS. By default ,the wizard will try to create filesystem type as VMFS5 and this filesystem can be able to support up to 2TB LUNS. If you want that datastore to be accessed across VMware ESX/ESXi version 5.0 and lower , then you need to choose VMFS3 filesystem. You can also have an option to create NFS datastore which will be used to store ISO images and virtual machines snapshots.
Here we will see how we can create a new ESXi datastore using the ISCSI LUNS.
1. Login to vSphere Web-client .(Open a browser and enter the vCenter IP address)
2.Click on the datastore to create it .
3.Select the datastore type .
4.Enter the datastore name select the ISCSI disks.(Below screen shot shows datastore name as “Datastore”.Actually i have changes to “UnixArenaDS1”)
5.Select the VMFS version .
6.Click on all available partitions and allocating the complete disk space to UnixArenaDS1 datastore.
7.Here is the summary of the new Datastore.
8.Click to finish the wizard.
The ISCSI-based datastore is created. It is available to the ESXI hosts to for VM provisioning.
Thank you for visiting UnixArena.
