Assign Storage Volumes
The "Assign/Unassign Storage Volumes" feature in QuantaStor allows users to assign or unassign storage volumes to specific hosts or servers within the storage environment. This feature enables administrators to control which hosts have access to particular storage volumes and manage the allocation of storage resources to different servers.
You can assign volumes to any Host using this dialog, there's another similar dialog for assignment to Host Groups. Simply select the volumes to be assigned, move them to the group on the right, and press OK.
Assignment of Storage Volumes to one or more Hosts and Host Groups enables access to the Storage Volumes via the Host Initiators associated with the Hosts. QuantaStor does not have an open-access mode where storage can be access by any host. All Storage Volumes must be assigned to one or more hosts to enable those hosts to login via iSCSI, FC or NVMeoF.
CAUTION: Storage Volumes that have been formatted with standard filesystems (not clustered filesystems) should never be assigned to more than one host at the same time. For example, two Windows hosts directly accessing a Storage Volume via iSCSI can quickly corrupt the filesystem as the systems are not coordinating their activities. Hypervisors like VMware, HyperV and cluster filesystems like OCFS2 are designed with distributed locking and are safe to use from multiple hosts accessing the same filesystem via iSCSI. In contrast, ext3/ext4, xfs, ufs, ntfs and many others are not designed to be mounted by multiple hosts simultaneously.
