Hotfix XS61E001 for XenServer 6.1.0

It’s not that long ago that Citrix has released version 6.1.0 for it’s XenServer product. Today they have released the first hotfix for this version.

This hotfix resolves the following issues:

After installing XenServer 6.1.0, multipathing will only use one path for Software iSCSI on arrays which contain the same IQN on multiple target portals. As a result, customers will see only one active path and will not successfully failover in the event of an infrastructure issue. This hotfix resolves this issue.

NOTE: Customers who are currently experiencing this problem should detach and re-attach the Storage Repositories (SRs) after applying the hotfix. However, customers who cannot detach and re-attach the SR, should refer to CTX135277 – Workaround for the Multipathing Behavior Change in XenServer 6.1.0 for a temporary workaround.

You can download the hotfix (and find installation instructions) here at the Citrix Knowledge Base.

Hotfix XS60E022 for XenServer 6.0

Citrix has released the 22nd hotfix for XenServer version 6.0. This latest hotfix includes and replaces (supersedes) hotfix XS60E017.

This fix resolves the following issues:

After installing CTX134870 – Hotfix XS60E017 – For XenServer 6.0, multipathing will only use one path for Software iSCSI on arrays which contain the same IQN on multiple target portals. As a result, customers will see only one active path and will not successfully failover in the event of an infrastructure issue. This hotfix resolves this issue.

In addition, this hotfix also includes fixes released in CTX131745 – Hotfix XS60E003 – For XenServer 6.0, CTX133961 – Hotfix XS60E016 – For XenServer 6.0, and CTX134870 – Hotfix XS60E017 – For XenServer 6.0.

NOTE: Customers who are currently experiencing this problem should detach and re-attach the Storage Repositories (SRs) after applying the hotfix. However, customers who cannot detach and re-attach the SR, should refer to CTX135274 – Multipath Workaround for Customers Affected by XenServer Hotfix XS60E017 for a temporary workaround.

Hotfix XS602E011 for XenServer 6.0.2

Citrix has released hotfix number 11 for XenServer 6.0.2.

This hotfix resolves the following issues:

  1. Attempts to read the metadata volume of an attached Storage Repository (SR) after the reboot of a multipath-enabled XenServer host, can cause an error and display the Error in Metadata volume Operation on SR error message.
  2. Storage may take several minutes to become available when using the Dell™ PowerVault™ MD32xxi Storage Arrays with LVMoiSCSI.
  3. XenServer may not discover all available LUNs when using wildcard IQN on storage arrays which do not support IQNs across multiple target portals. This occurs when using iSCSI storage arrays with multiple controllers, each managing their own LUNs.
  4. When booting a XenServer host, or re-attaching an iSCSI SR that contains a failed iSCSI path, the SR may fail to connect.

In addition, this hotfix also includes fixes released in CTX132823 – Hotfix XS602E001 – For XenServer 6.0.2, CTX133166 – Hotfix XS602E003 – For XenServer 6.0.2, CTX133812 – Hotfix XS602E005 – For XenServer 6.0.2 and CTX134479 – Hotfix XS602E007 – For XenServer 6.0.2. This means that you will not have to install these hotfixes before you can implement this hotfix. Only reason I see this is usefull is in a clean install of XenServer 6.0.2. In an existing environment I dare to hope you have already implemented these hotfixes by now… Continue reading “Hotfix XS602E011 for XenServer 6.0.2”

Hotfix XS60E019 for XenServer 6.0

Citrix has released the 19th update for its XenServer 6.0 platform. This hotfix resolves a stack overflow condition related to logging, which causes Windows Virtual Machines (VMs) to hang indefinitely.

Installing the Hotfix

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to install this update. Once the update has installed, the server must be restarted for it to take effect. As with any software update, please back up your data before applying this hotfix. Citrix recommends updating all hosts within a pool sequentially. Upgrading of hosts should be scheduled to minimize the amount of time the pool runs in a “mixed state” where some hosts have been upgraded and some have not. Running a mixed pool of updated and non-updated hosts for general operation is not supported.

Installing the update using XenCenter Continue reading “Hotfix XS60E019 for XenServer 6.0”

Hotfix XS602E010 for XenServer 6.0.2

Citrix has released the 10th hotfix for its XenServer 6.0.2 platform.

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  1. Customers may experience a delay when booting a Virtual Machine (VM) from a PVS Server. This hotfix changes the way the PVS device is detected and resolves the iterative delays that may occur during the first stage of the boot process of a PVS device.
  2. Running more than two DHCP servers when attempting to boot a VM from a network, can cause the VM to incorrectly wait for a reply from the DHCP server and eventually time out.
  3. Attempting to boot VMs from a network where the boot files are hosted on a server other than the DHCP server, can cause the VM boot to fail. Continue reading “Hotfix XS602E010 for XenServer 6.0.2”

XenServer conversion manager

With the release of the XenServer 6.1 version Citrix also released a new tool called XenServer conversion manager.

Getting Started with VMware Migration

Citrix XenServer Conversion Manager helps you convert workloads from VMware to XenServer by copying batches of VMware virtual machines to your XenServer environment.

Limitations

This section details limitations for XenServer Conversion Manager that apply to this release. For information about troubleshooting converted virtual machines, see the XenServer Conversion Manager Guide.

Limitations

  • Unlicensed Source Hypervisor. XenServer Conversion Manager cannot convert a virtual machine on an unlicensed vSphere ESX Server or vSphere ESXi Server.
  • Domain Controller. Citrix does not recommend using XenServer Conversion Manager to convert a source VM containing a Domain Controller. XenServer Conversion Manager can only “fix” or configure a Windows VM to start in XenServer if its virtual disks are formatted with NTFS.
  • Encryption. XenServer Conversion Manager cannot convert a VMware virtual machine that includes virtual disks with encrypted file systems.
  • Certificates. XenServer Conversion Manager does not verify the certificate on the XenServer Conversion Manager Virtual Appliance. The XenServer Conversion Manager Virtual Appliance does not verify certificates on vSphere ESX Server, vSphere ESXi Server, and vCenter Server.
  • Conversion Limits. XenServer Conversion Manager can accept up to 500 VMs at a time in a conversion job. The XenServer Conversion Manager converts one VM at a time.
  • Guest Network Settings. Settings of guest virtual network interfaces may change after the conversion. For example, the network name may change, IPv4 may become enabled, and IPv6 may become enabled.

For XenServer Conversion Manager set-up instructions, see the XenServer Conversion Manager Guide.

To set up XenServer Conversion Manager, obtain the XenServer Conversion Manager download package from the XenServer Tools page on Citrix.com (requires a My Citrix ID).

New hotfix XS60E017 for XenServer 6.0

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  1. When creating a Storage Repository (SR) or a Virtual Disk (VDI), predefined XML entities (for example &, <, >, “, ‘) entered into the Name and Description fields, are written directly into the SR metadata. Any subsequent actions such as creating an SR or a VDI will fail with an error message, as the XML parser fails to parse metadata if it contains predefined XML entities.
  2. If there is a failure or a change in the number of paths to storage, attempts to create or destroy a VDI on an LVM-based SR may fail and will display the following error message: Error in Metadata Volume Operation on SR. The VDI will be created, but will lack a Name or Description.
  3. If multipath is active, on some storage arrays an error may occur when reading the Metadata Volume during an SR attach and display the following error message: Error in Metadata Volume Operation on SR.
  4. Storage may take several minutes to become available when using Dell PowerVault MD32xxi Storage Arrays with LVMoiSCSI
  5. Xapi frequently hangs pool slaves due to exceeding the number of sessions on the Pool Master.
  6. An SR may fail to connect when the XenServer host is booted with one failed iSCSI path when using Hitachi or Compellent storage arrays.
  7. XenServer may not discover all of the available LUNS when using the wildcard IQN. This occurs when using Compellent storage arrays via iSCSI.
  8. Improvements to the XenCenter Update functionality; customers are correctly notified in XenCenter when new XenServer Tools are available.

In addition, this hotfix includes the following previously released hotfixes.

NOTE: Customers MUST install Hotfix XS60E001 – For XenServer 6.0 before attempting to apply this hotfix. Continue reading “New hotfix XS60E017 for XenServer 6.0”
