HP Storage Provisioning Manager (SPM) Version 1.2 User Guide

Cannot communicate with array or import storage volumes
Symptom–When defining a new array in SPM, attempting to import storage volumes, or performing
other array/volume operations, one of the following error messages appear:
• Communication Error - Unable to communicate with the device (See log
for details)
• ESA hostname is 'null' — A valid host name must be specified in HP.Ar-
cadia.ServiceWindowsService.exe.userconfig (<ESAHostname> element)
Possible cause–The first error message is the more common issue. It indicates broken communication
paths between SPM and the Extensible Storage Adapter layer that performs the SMI-S operations or
OO workflows, or between ESA and the device manager, or between the device manager and the
device. The log usually contains more information that can help pinpoint the problem. There could
be an issue with the Command View credentials, or the port being used by Command View. This
error also appears if there is a typo in the host name/IP.
Suggested action–There are a variety of possible corrective actions based on the root cause of the
issue (for example, Command View credentials or port usage). Consider the appropriate actions listed
below.
• Validate the credentials supplied for HP Command View EVA.
• Determine if HP Command View EVA is running on the same CMS (Central Management Server)
as HP SIM. When they are on the same server, a conflict exists because both Command View
and the HP SIM WMI Server use ports 5988 (unsecure) and 5989 (secure) by default. As noted
in the HP BladeSystem Matrix Setup and Installation Guide, this port conflict must be resolved by
adjusting the Command View port:
• The port being used by EVA SMI-S is specified in the file C:\Program Files\Hewlett-
Packard\SMI-S\CXWSCIMOM\config\cxws.properties.
• The value should be set to an unused value greater than or equal to port number 60000 and
less than 65536). For example, the cxws.http.port value is set to 60988 and cxws.ht-
tps.port value is set to 60989.
• If the port value remains set to the default values, make appropriate adjustments as specified
in the setup and install guide.
• Check the SPM log files. In the SPM interface, select Catalog > View Logs. The SPM operational
and audit logs appear in a new browser window. The Operational logs contain error events.

Volume created read-only and yet presented read-write
Symptom–Volume was created or presented in the array interface as read-only and yet is presented
by SPM as read-write.
Possible cause–When SPM performs volume presentation, it grants read-write access to the volume.
If you are using read-only volumes, be aware of this limitation and consider the suggested actions
below.
Suggested action–
1. Turn off the ability to modify presentation for all groups and users on a read-only volume. In SPM,
enter the volume properties screen and select the Security tab. Disable the "Volume Modify
Presentation" access right for the volume.
