Parameter Description

This parameter enables auto-load balancing on the controller. To enable the option, set this parameter to TRUE . To disable the option, set this parameter to FALSE .

Note: When the Automatic Load Balancing feature is enabled, the Host Connectivity Reporting feature will also be enabled.
autoSupport schedule Sets the daily and weekly times and days of the week that AutoSupport messages are sent.

The setting for automatically collecting support data each time the firmware detects a critical MEL event. This parameter has these values:

  • enable – Turns on the collection of support data
  • disable – Turns off the collection of support data

Use this parameter under these conditions only:

  • The AutoSupport (ASUP) feature is not available on the storage array

  • To support configurations on storage arrays that previously used this parameter

Note: You cannot use this parameter with the ASUP commands.
autoSupportMaintenanceWindow Turns on or turns off the AutoSupport maintenance window feature and configures the feature.
cacheBlockSize The cache block size that is used by the controller for managing the cache. Valid values are 4 (4 KB), 8 (8 KB), 16 (16 KB), or 32 (32 KB).
cacheMirrorDataAssuranceCheckEnable This parameter enables cache mirror data assurance check on the controller. To enable the option, set this parameter to TRUE . To disable the option, set this parameter to FALSE .

The percentage of unwritten data in the cache that causes a cache flush. Use integer values from 0 to 100 to define the percentage. The default value is 80 .

controllerHealthImageAllowOverWrite Sets a flag on a controller to allow a new controller health image to overwrite an existing controller health image on storage arrays that support the controller health image feature.
defaultHostType The default host type of any unconfigured host port to which the controllers are connected. To generate a list of valid host types for the storage array, run the show storageArray hostTypeTable command. Host types are identified by a name or a numerical index. Enclose the host type name in double quotation marks (" "). Do not enclose the host type numerical identifier in double quotation marks.
directoryServer Updates the directory server configuration, including role mappings.
externalKeyManagement Configures the external key management server address and port number
failoverAlertDelay The failover alert delay time in minutes. The valid values for the delay time are 0 to 60 minutes. The default value is 5 .
hostConnectivityReporting This parameter enables host connectivity reporting on the controller. To enable the option, set this parameter to enable . To disable the option, set this parameter to disable .
Note: If you attempt to disable Host Connectivity Reporting when Automatic Load Balancing is enabled, you receive an error. First disable the Automatic Load Balancing feature, then disable the Host Connectivity Reporting feature.
Note: You can keep Host Connectivity Reporting enabled when Automatic Load Balancing is disabled.
icmpPingResponse This parameter turns on or turns off Echo Request messages. Set the parameter to TRUE to turn on Echo Request messages. Set the parameter to FALSE to turn off Echo Request messages.
isnsIPv4ConfigurationMethod The method that you want to use to define the iSNS server configuration. You can enter the IP address for the IPv4 iSNS servers by selecting static . For IPv4, you can choose to have a Dynamic Host Configuration Protocol (DHCP) server select the iSNS server IP address by entering dhcp . To enable DHCP, you must set the isnsIPv4Address parameter to .
isnsIPv6Address The IPv6 address that you want to use for the iSNS server.

The IP address that you want to use for the iSNS server listening port. The range of values for the listening port is 49152 to 65535 . The default value is 53205 .

The listening port resides on the server and performs these activities:

  • Monitors incoming client connection requests

  • Manages traffic to the server

When a client requests a network session with a server, the listener receives the actual request. If the client information matches the listener information, then the listener grants a connection to the database server.


This parameter lists the storage array as an iSCSI target on the iSNS server. To register the storage array on the iSNS server, set this parameter to TRUE . To remove the storage array from the iSNS server, set this parameter to FALSE .

Note: You cannot use the isnsRegistration parameter with any other parameter when running the set storageArray command.

For more information about iSNS registration, refer to the set storageArray isnsRegistration command.

learnCycleDate Sets controller battery learn cycles.
localUsername Allows you to set a local user name password or a SYMbol password for a particular role.
loginBanner Allows you to upload a text file to be used as a login banner. The banner text can include an advisory notice and consent message, which is presented to users before they establish sessions in ThinkSystem System Manager or before they run commands
managementInterface Changes the management interface of the controller. Change the management interface type to enforce confidentiality between the storage array and its management software or to access external tools.
mediaScanRate The number of days over which the media scan runs. Valid values are disabled , which turns off the media scan, or 1 day to 30 days, where 1 day is the fastest scan rate, and 30 days is the slowest scan rate. A value other than disabled or 1 to 30 does not allow the media scan to function.
odxEnabled Turns on or turns off Offloaded Data Transfer (ODX) for a storage array.
passwordLength Allows you to set the minimum required length for all new or updated passwords. Use a value between 0 and 30.
pqValidateOnReconstruct Modifies the P/Q validate on reconstruction capability.
redundancyMode Use simplex mode when you have a single controller. Use duplex mode when you have two controllers.
revocationCheckSettings Allows you to enable or disable revocation checking, and configure an Online Certificate Status Protocol (OCSP) server.
securityKey Sets the internal security key that is used throughout the storage array to implement the Drive Security feature.
Note: Used for an internal security key. When an external key management server is used, use the create storageArray securityKey command.
symbol Allows you to set a SYMbol password for a particular role.
syslog Allows you to change the syslog server address, protocol, or port number.
time Sets the clocks on both controllers in a storage array by synchronizing the controller clocks with the clock of the host from which you run this command.
trayPositions A list of all of the tray IDs. The sequence of the tray IDs in the list defines the positions for the controller tray and the drive trays in a storage array. Valid values are 0 to 99 . Enter the tray ID values separated with a space. Enclose the list of tray ID values in parentheses. For storage arrays where the controller tray has a predefined identifier that is not in the range of valid tray position values, use the controller value.
unnamedDiscoverySession Enables the storage array to participate in unnamed discovery sessions.
userLabel The name for the storage array. Enclose the storage array name in double quotation marks (" ").
userSession Allows you to set a timeout in System Manager , so that users' inactive sessions are disconnected after a specified time.
vaaiEnabled Turns on or turns off VMware vStorage API Array Architecture (VAAI) for a storage array


Except for the isnsRegistration , when you use this command you can specify one or more of the optional parameters.

Auto Support data

Note: You cannot use this parameter with the ASUP commands.

When enabled, the set storageArray autoSupportConfig command causes all configuration and state information for the storage array to be returned each time a critical Major Event Log (MEL) event is detected. The configuration and state information is returned in the form of an object graph. The object graph contains all relevant logical and physical objects and their associated state information for the storage array.

The set storageArray autoSupportConfig command collects configuration and state information in this way:

You can run the set storageArray autoSupportConfig command on more than one storage array.

Cache block size

When you define cache block sizes, use the 4-KB cache block size for storage arrays that require I/O streams that are typically small and random. Use the 8-KB cache block size when the majority of your I/O streams are larger than 4 KB but smaller than 8 KB. Use the 16-KB cache block size or the 32-KB cache block size for storage arrays that require large data transfer, sequential, or high-bandwidth applications.

The cacheBlockSize parameter defines the supported cache block size for all of the volumes in the storage array. Not all controller types support all cache block sizes. For redundant configurations, this parameter includes all of the volumes that are owned by both controllers within the storage array.

Cache flush start

When you define values to start a cache flush, a value that is too low increases the chance that data needed for a host read is not in the cache. A low value also increases the number of drive writes that are necessary to maintain the cache level, which increases system overhead and decreases performance.

Default host type

When you define host types, if Storage Partitioning is enabled, the default host type affects only those volumes that are mapped in the default group. If Storage Partitioning is not enabled, all of the hosts that are attached to the storage array must run the same operating system and be compatible with the default host type.

Media scan rate

Media scan runs on all of the volumes in the storage array that have Optimal status, do not have modification operations in progress, and have the mediaScanRate parameter enabled. Use the set volume command to enable or disable the mediaScanRate parameter.


Passwords are stored on each storage array. For best protection, the password must meet these criteria:

Note: If you are using full disk encryption drives in your storage array, you must use these criteria for your storage array password.
Note: You must set a password for your storage array before you can create a security key for encrypted full disk encryption drives.
