  • Page 11: About The Command Line Interface

    The command line interface gives you direct access to a script engine utility in the Dell PowerVault Modular Disk Storage Manager software (MD Storage Manager). The script engine reads the commands, or runs a script file, from the command line and performs the operations instructed by the commands.

  • Page 12: Usage Notes

    A CLI command consists of the following elements: • The term SMcli • Storage array identifier • Parameters • Script commands The following syntax is the general form of a CLI command: SMcli storageArray parameters script-commands; where, SMcli invokes the command line interface storageArray is the host name or IP address of the storage array parameters are the CLI parameters that define the environment and purpose of the command script-commands are the commands or name of the script file containing the script commands...

The community is the SNMP community name for the trap, and the host is the IP address or DNS host name of the system to which you want the trap sent.

  • Page 19: Exit Status

    When an exception occurs while executing a command, the CLI automatically saves the error information to a file named excprpt.txt. The CLI attempts to place excprpt.txt in the directory specified by the system property devmgr.datadir, which by default is the "client/data" directory under the main installation directory in Windows and the /var/opt/SM directory in Linux.

  • Page 20: Usage Examples

    Status Value Meaning The wrong management station was specified. The command was not available. The device was not in the configuration file. An error occurred while updating the configuration file. An unknown host error occurred. The sender contact information file was not found. The sender contact information file could not be read.
  • Page 21 This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example. The parameter runs the file without checking syntax. Executing an SMcli command without checking syntax enables the file to run more quickly; however, the SMcli command may not execute correctly if the syntax is incorrect. SMcli -n Example -f scriptfile.scr -e This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example.

  • Page 23: About The Script Commands

    About The Script Commands You can use the script commands to configure and manage a storage array. The script commands are distinct from the command line interface (CLI) commands; however, you enter the script commands using the command line interface. You can enter individual script commands, or run a file of script commands.

The general form of the syntax for operand-data is as follows: (object-type | allobject-types | [qualifier] (object-type [identifier] {object-type...

  • Page 25: Script Command Synopsis

    Statement data is in the form of attribute=value (such as raidLevel=5), an attribute name (such as batteryInstallDate), or an operation name (such as consistencyCheck). Script Command Synopsis Because you can use the script commands to define and manage the different aspects of a storage array (such as host topology, physical disk configuration, RAID controller module configuration, virtual disk definitions, and disk group definitions), the actual number of commands is extensive.

    Configuring A Storage Array This chapter explains how to run script commands from the command line to create a virtual disk from a group of physical disks and how to configure a redundant array of independent disks (RAID) storage array. This chapter assumes that you understand basic RAID concepts and terminology.

  • Page 34: Determining What Is On Your Storage Array

    Determining What Is On Your Storage Array Even when you create a configuration on a previously unconfigured storage array, you still need to determine the hardware and software features that must be included with the storage array. When you configure a storage array with an existing configuration, you must ensure that your new configuration does not inadvertently alter the existing configuration, unless you are reconfiguring the entire storage array.

    Using The Create Virtual Disk Command The create virtualDisk command enables you to create new virtual disks in the storage array in three ways: • Create a new virtual disk while simultaneously creating a new disk group to which you assign the physical disks. •...
  • Page 37 The command in this example automatically creates a new disk group and a virtual disk with the name Engineering_1. The disk group has a RAID level of 5 (RAID 5). The command uses three physical disks to construct the disk group. The virtual disk created has a capacity of 20 GB.

  • Page 38: Using The Auto Configure Command

    The freeCapacityArea parameter defines the free capacity area to use for the virtual disk. If a disk group has several free capacity areas, you can use this parameter to identify which free capacity area to use for virtual disk creation. You do not have to assign the entire capacity of the physical disks to the virtual disk. Assign any unused space to another virtual disk at another time.
  • Page 39 values that MD Storage Manager uses to create a storage array. Change any of the parameter values by entering new values for the parameters when you run the autoConfigure storageArray command. If you are satisfied with the parameter values that the show storageArray autoConfiguration command returns, run the autoConfigure storageArray command without new parameter values.

  • Page 40: Modifying Your Configuration

    The command in this example creates a storage array configuration that uses SAS physical disks set to RAID level 5. Three disk groups are created. Each disk group consists of eight physical disks configured into four virtual disks. The storage array has two hot spares, and segment size for each virtual disk is 8 KB. Modifying Your Configuration After creating your initial configuration, modify the properties of the configuration to ensure that it meets your requirements for data storage.

  • Page 65 You can select snapshot virtual disks as the source virtual disk for a virtual disk copy. Selecting a snapshot virtual disk is a good use of this feature, because it enables complete backups without significant impact to the storage array I/O. However, some I/O processing resources are lost to the copy operation.

  • Page 67: Using The Remote Replication Premium Feature

    Using The Remote Replication Premium Feature The Remote Replication premium feature provides for online, real-time replication of data between storage arrays over a remote distance. In the event of a disaster or a catastrophic failure on one storage array, you can promote the second storage array to take over responsibility for computing services.

  • Page 68: Replication Repository Virtual Disks

    Replication Repository Virtual Disks A replication repository virtual disk is a special virtual disk in the storage array that is created as a resource for the RAID controller module owner of the primary virtual disk in a remote replicated pair. The RAID controller module stores replication information on this virtual disk, including information about remote writes that are not yet complete.

  • Page 69: Link Interruptions Or Secondary Virtual Disk Errors

    host write requests are written to the primary virtual disk and then copied to the secondary virtual disk. After the host write request has been written to the primary virtual disk and the data has been successfully copied to the secondary virtual disk, the RAID controller module removes the log record on the replication repository virtual disk.

  • Page 70: Creating A Remote Replicated Pair

    owner of the primary virtual disk receives a write request from a host, the RAID controller module first logs information about the write to a replication repository virtual disk. The RAID controller module then writes the data to the primary virtual disk.

  • Page 71: Enabling The Remote Replication Premium Feature

    – A full synchronization at the high synchronization priority level takes approximately twice as long as a full synchronization at the highest synchronization priority level. • When the replicated virtual disk pair is in a Synchronization in Progress state, all host write data is copied to the remote system.
  • Page 72 Activating the Remote Replication Premium Feature with User-Assigned Physical Disks Activating the Remote Replication premium feature by assigning the physical disks provides flexibility in defining your configuration by letting you choose from the available physical disks in your storage array.

    between a primary virtual disk and a secondary virtual disk does not affect any of the existing data on either virtual disk. The link between the virtual disks is removed, but the primary virtual disk still continues normal I/O operations. Later, you can establish the replication relationship between the two virtual disks and resume normal replication operations.

  • Page 77: Snapshot Virtual Disks

    In addition to running with the premium features, you can also run the Remote Replication premium feature while running Storage Partitioning and Virtual Disk Expansion (VDE). Snapshot Virtual Disks A snapshot virtual disk is a point-in-time image of a virtual disk. It is typically created so that an application, such as a backup, can access the snapshot virtual disk and read the data while the source virtual disk remains online and accessible to hosts.

  • Page 78: Virtual Disk Expansion

    After you create a virtual disk copy, the target virtual disk automatically becomes read‑only to hosts to ensure that the data is preserved. Hosts that have been mapped to a target virtual disk do not have write access to the virtual disk, and any attempt to write to the read-only target virtual disk results in a host I/O error.

  • Page 79: Maintaining A Storage Array

    Maintaining A Storage Array Maintenance covers a broad spectrum of activities. Its goal is to keep a storage array operational and available to all hosts. This chapter provides descriptions of command line interface (CLI) and script commands that you can use to perform storage array maintenance.

    Performance Tuning Over time, as a storage array exchanges data between the hosts and physical disks, its performance can degrade. Monitor the performance of a storage array and make adjustments to the storage array operational settings to improve performance. Monitoring Performance Monitor the performance of a storage array by using the save storageArray performanceStats command.

  • Page 83: Changing Raid Levels

    Changing RAID Levels When creating a disk group, define the RAID level for the virtual disks in that group. You can later change the RAID level to improve performance or provide more secure protection for your data. To change the RAID level, run the following command: set diskGroup [diskGroupNumber] raidLevel=(0|1|5|6) where, diskGroupNumber is the number of the disk group for which to change the RAID level.

    Collecting Physical Disk Data To gather information about all the physical disks in a storage array, run the save allPhysicalDisks command. This command collects sense data from all the physical disks in a storage array and saves the data to a file. The sense data consists of statistical information maintained by each of the physical disks in the storage array.

  • Page 85: Setting Raid Controller Module Operational Mode

    Setting RAID Controller Module Operational Mode A RAID controller module has three operational modes: • Online • Offline • Service CAUTION: Placing a RAID controller module offline can cause loss of data. Placing a RAID controller module online sets it to the Optimal state and makes it active and available for I/O operations.

    When you initialize a physical disk, all old disk group and virtual disk information is erased, and the physical disk is returned to an unassigned state. Returning a physical disk to an unassigned state adds unconfigured capacity to a storage array. You can use this capacity to create additional disk groups and virtual disks. To initialize a physical disk, run the following command: start physicalDisk [enclosureID,slotID] initialize enclosureID and slotID are the identifiers for the physical disk.

    Whenever a security-enabled physical disk is powered on, it requires the correct security key from the RAID controller module before it can read or write data. So, a security-enabled physical disk uses two keys: the physical disk key that encrypts and decrypts the data and the security key that authorizes the encryption and decryption processes. The set storageArray securityKey command commits the security key to all of the RAID controller modules and security-enabled physical disks in the storage array.
