Issues Resolved In This Hotfix
When detaching an HBA Storage Repository (SR), and then attempting to reattach it using XenCenter, the reattach operation will fail with the message: “The SCSI id parameter is missing or incorrect”.
When using XenCenter to move a large disk to a different SR, the operation can time out and fail to complete.
System Alerts generated for XenServer v6.1.0 hosts display numerical alert severities. Customers should ignore these numerical severities as they are invalid for XenServer v6.1.0 hosts.
For XenServer v6.1.0 and earlier versions, the XenCenter License Manager can incorrectly report the license type as âFree Editionâ for paid-for editions (that is, Advanced, Enterprise, or Platinum).
When trying to join an unlicensed host to a licensed pool, XenCenter should offer to apply a license to the new host. This works correctly for XenServer v6.1.0 and earlier servers, but does not happen in v6.2.0. This means that the new host cannot join a pool until it is licensed separately.
Joining a licensed host to an unlicensed pool should not be possible, however XenCenter does not apply this rule to v6.2.0 hosts and allows the customer to attempt this operation.
In rare cases when a pool contains hosts with different license types, the pool’s license should be reported as the least privileged license in the pool. However XenCenter’s License Manager incorrectly lists the pool master’s license as the pool’s license type.
In a pool consisting of XenServer v6.1.0 or earlier hosts, it is impossible to apply a free license to the pool using XenCenter. This is because free licenses have to be applied to each host separately; XenCenter incorrectly lists the whole pool as one item in the License Manager.
When configuring High Availability (HA), XenCenter may not set the restart priority on all of the VMs, so they will not be protected to the required level. (It will only set the rows that are selected (blue) on the table of VMs and their restart priorities).
This hotfix also includes additional functionality for large deployments:
Adds creation of up to 50 new fibre-channel HBA SRs in a single step using an updated New SR wizard, with the following restrictions:
Customers who select greater than 50 SRs may find that the New SR wizard prematurely exits. Re-running the New SR wizard will create the remaining SRs.
In some circumstances, the automatic numbering of the new SRs may skip one of the sequenced numbers. However, all SRs are created.
The New SR wizard uses Hardware HBA virtual disk storage (n) as the naming seed, even if customers select a different name.
When adding HBA SRs to a pool of XenServer hosts, before running the New SR wizard, customers should ensure that each LUN is mapped to all hosts in the pool
Adds a feature to attach multiple fibre channel LUNs to reduce downtime in the event of a disaster.
