VMware 3V0-22.21 Dumps

The Update Manager displays system managed baselines that are generated by vSAN. These baselines appear by default when you use vSAN clusters with ESXi hosts of version 6.0 Update 2 and later in your vSphere inventory. If your vSphere environment does not contain any vSAN clusters, no system managed baselines are created.

The system managed baselines automatically update their content periodically, which requires Update Manager to have constant access to the Internet. The vSAN system baselines are typically refreshed every 24 hours.

You use system managed baselines to upgrade your vSAN clusters to recommended critical patches, drivers, updates or the latest supported ESXi host version for vSAN.

System managed baselines cannot be edited or deleted. You do not attach system managed baselines to inventory objects in your vSphere environment. You can create a baseline group of multiple system managed baselines, but you cannot add any other type of basline to that group. Similarly, you cannot add a system managed baseline to a baseline group that contains upgrade, patch, and extension baselines.

Authentication and authorization govern access. vCenter Single Sign-On supports authentication, which means it determines whether a user can access vSphere components at all. Each user must also be authorized to view or manipulate vSphere objects.

vSphere supports several different authorization mechanisms, discussed in Understanding Authorization in vSphere. The focus of the information in this section is how the vCenter Server permission model works and how to perform user management tasks.

vCenter Server allows fine-grained control over authorization with permissions and roles. When you assign a permission to an object in the vCenter Server object hierarchy, you specify which user or group has which privileges on that object. To specify the privileges, you use roles, which are sets of privileges.

Initially, only the administrator user for the vCenter Single Sign-On domain, administrator@vsphere.local by default, is authorized to log in to the vCenter Server system. That user can then proceed as follows:

• Add an identity source in which users and groups are defined to vCenter Single Sign-On. See the Platform Services Controller Administration documentation.
• Give privileges to a user or group by selecting an object such as a virtual machine or a vCenter Server system and assigning a role on that object for the user or group.

• Cannot create a new datastore from vCenter Server or directly from the vSphere Client
• Creating a new datastore fails
• The Add Storage Wizard reports the error:An error occurred during host configuration.Call “HostDatastoreSystem.QueryVmfsDatastoreCreateOptions” for object “ha-datastoresystem” on ESXi “xxx.xxx.xxx.xx″ failed.An internal error occurred in the vsphere client.

 Cause

This issue may occur if:

• The size of the LUN is more than 2TB - 512 bytes. The maximum LUN size in vSphere 4 is 2TB - 512 bytes. For more information on this limitation, see Troubleshooting a LUN that is extended in size past the 2TB/2047GB limit (1004230).
• The LUN being presented was used as an RDM earlier and does not have a valid partition table.
• The LUN being presented was used as a disk device on an other operating system and does not have a valid partition table.
• The LUN contains a GPT partition that cannot be removed.

 Resolution

To prevent this issue:

• Ensure that the LUN size is less than 2TB - 512 bytes or 2047GB. If the LUN is larger then 2TB - 512 bytes, delete it from your Storage Array and recreate it with a size less than the 2TB - 512 bytes limit.
• If the disk was used by another operating system in the past (I.E.: it was an RDM, or Linux, FreeBSD, or other filesystem) or contains a GPT partition, you must delete the partition information.For more information
