Preparing storage devices

This section describes how to prepare NetApp and EMC storage devices for monitoring.

For other device types, refer to the ZenPack catalog documentation.

Legacy NetApp filers

Resource Manager uses SNMP to monitor legacy NetApp filers that do not support the Data ONTAP® API (ZAPI).

The data gathered are approximate because the values for many objects (Aggregate, Volume, Plex, and RAID group) are not exposed by the NetApp MIB.

To prepare a legacy NetApp filer for monitoring, verify that SNMPv2 is installed, and then start an SNMP agent.

Recent NetApp filers

Resource Manager uses HTTP to monitor NetApp filers that support the Data ONTAP® API (ZAPI).

To prepare a recent NetApp filers for monitoring, verify the following conditions:

  • The filer is running in 7-Mode or C-Mode.
  • A supported version of ZAPI is installed and enabled. The minimum required version is 8.x.
  • The user name and password of your account on the filer is authorized to use ZAPI.

EMC storage arrays

Resource Manager uses the Web-Based Enterprise Management (WBEM) protocol to send queries to EMC Storage Management Initiative Specification (SMI-S) providers that are associated with EMC VMAX and VNX storage arrays.

To prepare EMC arrays for monitoring:

  • At least one EMC SMI-S provider must be running for each type of array to monitor. (The VMAX and VNX data models are different.)
  • Before adding an SMI-S provider to Resource Manager, Zenoss recommends that you confirm that it is responding to requests.
  • You need the following information:
    • user name and password for an account that is authorized to collect data on each SMI-S provider
    • IP address of each SMI-S provider
    • port number at which each SMI-S provider listens for requests
    • whether to use SSL

When statistics logging is disabled on the EMC device, graphs for component types of EMC arrays display NaN. The logging feature has a low default timeout value and must be set to a higher value or turned on again periodically.

Verifying an SMI-S provider on EMC devices

To perform this procedure, you need a Linux host that has a network path to the SMI-S providers of the arrays to monitor.

Do not perform this procedure on the Resource Manager host.

Perform this procedure to verify that the SMI-S providers associated with EMC arrays are configured correctly, and are responding to WBEM queries from command line tools.

  1. Log in to a Linux host as root or as a user with superuser privileges.

  2. Install a WBEM command-line interface package, such as wbemcli.

  3. Verify the SMI-S provider. Replace the variables with values that are valid in your environment.

    wbemcli IP-Address:Port -u admin -p 'Password' -n root/emc --no-sslei('EMC_DiskDrive')

    The expected result is a list of Disk Drive classes.
