Summary

This patch fixes the following issues:

• When the ESX host boots, the megaraid_sas driver heap gets depleted when claiming 4 LSI SAS RAID controllers on IBM System x3950 M2 Athena servers. This issue might cause the ESX host to stop booting. The fix increases the heap size for the megaraid_sas driver from 8 MB to 16 MB.

• The mptscsi_2xx driver limits the discovery of targets to 63 SAS devices per LSI Serial Attached SCSI (SAS) host bus adapter (HBA). This fix increases the number of targets to the value returned by the HBA firmware.

Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table, above.

Patch Download and Installation

Note: All virtual machines on the ESX host must be either shut down or migrated using VMotion before applying the patch. A reboot of the ESX host is required after applying this patch.

See the VMware Update Manager Administration Guide for instructions on using Update Manager to download and install patches to automatically update ESX 3.5 hosts.

To update ESX 3.5 hosts when not using Update Manager, download the most recent patch bundle from http://www.vmware.com/download/vi/vi3_patches_35.html and install the bundle using esxupdate from the command line of the host. For more information, see the ESX Server 3 Patch Management Guide.
