The following issues have been observed in CA AppLogic releases but are extremely difficult to reproduce (if at all) and have only been observed once or twice. If any of these issues appear on your grid, please send a bug report to CA describing which problem occurred and which CA AppLogic commands were executed that led to the failure.
A server in the grid rebooted on its own due to a crash in the Linux kernel in dom0 of the server. This would not cause the entire grid to fail like in previous CA AppLogic releases; but could cause application downtime. In such a case CA AppLogic restarts the appliances that were running on the failed server on other servers in the grid. If this issue is observed on your grid, contact CA Support.
In CA AppLogic 2.4, there have been several cases where a server loses connection to the grid controller and reboots. This causes all of the appliances that were running on the server to be rescheduled on other servers in the grid and can also cause application downtime. It is unknown why the servers are losing their connections to the grid controller.
If the server's connection to the grid controller is dissolved, the server tries to reconnect to the grid controller and if successful, the server remains operational and there is no application downtime. If the server cannot reconnect to the grid controller for one minute, the server is rebooted and application downtime occurs. When a server loses its connection to the grid controller, a message is logged to the dashboard. If this problem is observed, contact CA Support.
On CA AppLogic, resizing 4 NTFS volumes at the same time caused all four volume resize operations to fail. This issue has been observed only once.
While NASR was replicating an 800MB file on a 1GB volume, the NASR appliance became unresponsive. CA is unable to reproduce this issue. If this issue is encountered on your grid, contact CA support.
User opened six graphical consoles to different windows appliances running on the grid (opened at the same time). Upon opening the seventh graphical console, one of the servers rebooted and rejoined the grid. The appliances that were running on the failed server were restarted on other servers within the grid. This issue has only been observed once.
We have identified the following known problems with the Backbone Fabric Controller (BFC) in this release:
su - bfcadmin
Important! After breaking this dependence, your system will be running without replica, so go back into the UI and establish another replica at the same or a different location.
Please do not use the “3t grid shutdown” command on a grid.
When this occurs, doing a “service nfs restart” on the BFC should resolve the problem.
If you get this message, simply hit the “Esc” key to continue the install.
If you are performing an unattended install with this version of the product, your password cannot contain a “=”
This bug could occasionally allow servers into grids that should be blocked. If the ports are properly configured, this problem will not be encountered.
If you need to use more than 256 characters, simply break those parameters into more than one update of the grid.
If the graphics rendering option is not set correctly in Internet Explorer 9, graphs in the BFC do not display correctly. Affected graphs appear in the BFC Dashboard, Grids, and Servers pages.
To fix this problem, in Internet Explorer 9 click Internet Options on the Tools menu. Click the Advanced tab and locate the Accelerated graphics section. Select the Use Software Rendering check box. Save your changes and restart IE.
If you need to set these many MACs to AutoDiscovery (blacklist) mode, it would be best to use Manual Configuration (whitelist) mode with 3.5.
Please ensure you have external IP addresses available when added servers to a BFC.
Due to this bug you cannot directly swap the controller and application IPs with each other in one step. If you must do this, first set them to some other values, then you may set them again to the intended values.
If you attempt to add a tagged network to an untagged grid via the API, the call will succeed, instead of returning 400 Bad Request.
When there is no download server configured (local download directory), we show versions as Downloaded and accept delete operations, but the delete is correctly a non-operation. Future releases will generate an error that describes why this action doesn’t do anything.
This is not really an error, just a confusing message.
You can use the API to add the same range multiple times, but you can use the UI to remove the duplicate ranges. (Leaving the duplicate ranges in place, however, will not case any problems.)
Since 3.7.0 has not been localized, the new parts of the application will only display English strings. The previously localized parts of the application (those that existed in 3.5) will still display the non-English strings as before.
On some Dell hardware you can enable a DRAC Virtual Media BIOS option. This feature allows you to boot from a virtual media device over the network. However, the CA AppLogic kernel may identify the virtual media device as a SCSI device and confuse the boot device name (what was "sda" becomes "sdb").
To avoid this problem, disable the DRAC Virtual Media option in the DRAC BIOS on your Dell hardware.
When you add or remove addresses to the list of MAC addresses in the BFC, limit the maximum number to 500. The MACs list is used in Discovery Mode to include servers (when set to Manual Configuration) or exclude servers (when set to Auto Discovery mode).
You can work with the list of MACs on the Administration page of the BFC on the Discovery tab. You can edit the list of servers, or can import a file with a list of servers. You can also set the MAC address list using the BFC API.
While AppLogic Xen grid servers support 3TB disks, AppLogic ESX grid servers support a maximum of 2TB disks. Servers with 3TB disks should not be chosen to run the ESX hypervisor otherwise grid creation will fail.
If you participated in the CA AppLogic 3.7 beta program then you must make sure that the beta version of CA AppLogic is present in your BFC’s download directory if you must execute the fallback procedure due to a failed upgrade.
