Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, see Citrix eDocs, the Citrix Product Documentation Library.

New Fixes in This Release

  1. Uploading the payload results in the following error message due to the violation of primary key constraint:

    “Cannot insert duplicate key in object ‘dbo.ctrx_session_autoreconnect’.”

    [From ES540ServerWX64001][#238149]

  2. When Worker 101 (Performance Upload) and Worker 2 (Database Maintenance) run at the same time, an upload is attempted even though the database is not available. Although the status of Worker 101 is displayed as successful, this situation results in the following payload error:

    “Invalid payload, no ENV data found”

    [From ES540ServerWX64001][#242200]

  3. When exporting the Session Counts report to Microsoft Excel, the exported data displays “#Value!” in the peak columns.

    [From ES540ServerWX64001][#253058]

  4. If multiple users connect to different XenApp servers and are assigned the same session id by the terminal server, the payload from one XenApp Server can overwrite the principal id of the other XenApp Server, resulting in incorrect EdgeSight report data.

    [From ES540ServerWX64001][#253168]

  5. Users can run the “Assets for a Device” report against devices for which they do not have user permissions.

    [From ES540ServerWX64001][#256871]

  6. If the initial attempt to upgrade a server from EdgeSight Version 5.2 to Version 5.3 or later fails, an error might occur when making subsequent upgrade attempts. The following error message appears in the MSI log:

    “Error -2147217900: failed to execute SQL string, error detail: Ambiguous column name ‘appid’., SQL key: SchemaPost530”

    [From ES540ServerWX64001][#LA0402]

  7. Running any of the following reports on Version 5.4 of EdgeSight Web server (Version 5.4.0.5107 or earlier) in the EdgeSight database might generate errors messages:

    • Process Errors
    • Process Errors for a User Group
    • Process Faults
    • Process Faults for a User Group

    The following error messages are observed:

    • An error occurred during the client rendering
    • An error has occurred during the report processing (rsProcessingAborted)
    • Cannot read the next data row for the dataset edgesight (rserrorreadingnextdatarow)
    • Arithmetic over flow error converting expression to data type int

    This occurs when the ID generated by the alert table (alert ID) exceeds the maximum integer value (2147483648).

    [From ES540ServerWX64001][#LA0760]

XenServer: Creating an ISO Partition on DOM0

Intro

I recently updated my lab machine to XenServer 6.0 and I wanted to create a local ISO repository on the DOM0 partition. I have 3 physical drives, one 250GB drive that holds the host partition and its backup and two 500GB drives that host VM’s. I know that only 8GB on the 250 GB drive are used for the host and its backup, so I wanted to create the local ISO repository in the remaining space.

Stop! Linux Time

Connect to the CLI of your XenServer.

fdisk –l shows my current partition tables

[root@MARLINSPIKE ~]# fdisk -l

Dom0 contains 3 partitions. The first is where the XenServer host resides. The second is the host backup. The final partition is the rest of the unused space on the 250GB drive. In my file system, this is /dev/sdc3. The following commands will format and mount this space as an ISO partition.


[root@MARLINSPIKE ~]# mkfs.ext3 /dev/sdc3
mke2fs 1.39 (29-May-2006)

4096000, 7962624, 11239424, 20480000, 23887872

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 32 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
[root@MARLINSPIKE]# mkdir /mnt/iso/
[root@MARLINSPIKE]# mount -t ext3 /dev/sdc3 /mnt/iso/
[root@MARLINSPIKE]# echo "/dev/sdc3 /mnt/iso ext3 defaults 1 1" >> /etc/fstab
[root@MARLINSPIKE]# xe-mount-iso-sr /mnt/iso -o bind

Now the new ISO partition shows up in my XenCenter console.
