Configuration of EMCRAIDDiskTest

This test monitors the current state, overall health, and the load-balancing capability of each disk in the EMC storage system. With the help of this test, administrators can not only identify failed disks, but can also predict the potential failure of a disk, so that efforts can be undertaken to avert the same. In addition, the test also points administrators to disks that are handling more I/O requests than the rest, thus shedding light on irregularities in the distribution of I/O load across disks and prompting administrators to fine-tune the load-balancing algorithm. In addition, the test also proactively alerts administrators to probable slowdowns in I/O processing by specific disks, thereby enabling administrators to initiate pre-emptive actions.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the IP address of the storage device in the HOST text box.

• Specify the port number at which the storage device listens in the PORT text box. By default, this value is NULL.

• The SMI-S Provider is paired with the EMC CIM Object Manager Server to provide an SMI-compliant interface for CLARiiON arrays. Against the USER and PASSWORD parameters, specify the credentials of a user who has been assigned Monitor access to the EMC CIM Object Manager Server paired with EMC CLARiiON's SMI-S provider.

• Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD text box.

• Set the SSL flag to Yes, if the storage device being monitored is SSL-enabled.

• By default, the ISEMBEDDED flag is set to False for an EMC CLARiiON device. Do not disturb this default setting.

• If the SMI-S provider has been implemented as a proxy, then such a provider can be configured to manage multiple storage devices. This is why, you will have to explicitly specify which storage system you want the eG agent to monitor. Since each storage system is uniquely identified by a SERIAL NUMBER, specify the same in the SERIALNUMBER text box. The serial number for an EMC CLARiiON device will be of the format, FCNMM094900059.

• Specify the namespace that uniquely identifies the profiles specific to the provider in use in the NAMESPACE text box. For EMC CLARiiON, this parameter will be set to root/emc by default.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
