Datasource hangs, if there is not free hdd capacity

I would suggest implementing the WARN_DISKFULL environmental variable for the data source to warn prior to the partition becoming full.  This will allow for corrective actions prior to the partition becoming full.  If the data source fails to attach I would suggest deleting the data source, clean up disk space or expand the partition, then recreate the data source.

From the EMC AutoStart 5.3 SP3 Administrator's guide:

WARN_DISKFULL — Used exclusively for the following types of data sources:  Shared Disk Device for Windows, EMC Mirroring for Windows, and UNIX File System type data sources. See “Receiving a warning notification by email when a disk is nearly full” on page 811 for a description of this variable's use and values.

Receiving a warning notification by email when a disk is nearly full

Under normal conditions, when a disk is full, the data source goes to a No Response state. If the data source is being used as a resource in a resource group, the data source’s No Response state causes the resource group to relocate. However, relocating does not solve the problem—the data source’s disk will still be full, which will cause the resource group to relocate over and over again. This condition can be confusing and difficult to troubleshoot. If you have no other means for identifying a disk that is nearing its capacity, AutoStart has a solution that will make it easier for you.

You can add an environment variable that will warn you when the disk nears 100% full so that you can take corrective action. It does this by sending a notification email as the disk nears capacity. This variable will also change the data source’s state to a Warning state, instead of No Response, and as a result the resource group will stay online and will not failover when this condition occurs.

Hi,

This is specifications of the data source response test.

Take offline a resource group.

It is necessary to disable the response test of the data source.

It comes to be able to do ATTACH by this.

After that, please increase the free space.
