EMC Solutions Enabler for VMAX Storage
To communicate with VMAX, Cisco UCS Director uses the EMC Solutions Enabler (SE). You must install a supported Windows-based or Linux-based EMC SE before you add your VMAX or VMAX3 storage system to Cisco UCS Director.
Windows-Based Solutions Enabler
Guidelines for SSHD Server Configuration
To set up an SSHD server, we recommend that you install Cygwin version 1.7.27, and use the SSH daemon on the host. Cygwin provides a Linux-like environment on Microsoft Windows. See Installing a Cygwin Package for information on downloading Cygwin and additional information about the SSHD server.
After you install the SSHD server on the Windows-based SE, modify the Path variable under System Variables to include the Solutions Enabler bin folder so that whoever uses SSH to get into the Windows SE can immediately run VMAX commands. After you install and configure the SSHD server, set up the new default paths to enable the user-installed software to override the system software.
Installing a Cygwin Package
Ensure that you install the packages fir Cygwin version 1.7.27 on a Windows-based host.
Step 1 | Download the Cygwin executable from http://www.cygwin.com/. |
Step 2 | While installing the Cygwin package on the package selection screen, select the openssh and openssl packages to install. |
Configuring the SSHD Server
Configuring System Environment Variables
Starting the Cygwin SSHD Service
Verifying SSH Access
Ensure that you can run the SYMCLI commands without providing the absolute path at the command prompt. You can verify SSH access using any SSH client.
Installing and Configuring a Linux-Based Solutions Enabler
![]() Note | You can add libraries and legacy libraries, such as glibc, to the VM. You need gatekeepers to serve as Raw Device Mappings (RDMs). Allow 6,000 to 8,000 mappings for each RDM. |
1. Create the base Linux image for the VM you will use.
2. Assign a few gatekeepers as RDMs.
3. Reboot the Linux VM.
4. From the EMC Powerlink site, download the EMC Solutions Enabler package for Linux and the Services Management Application System (SMAS) package se7310-Linux-i386-ni.tar.gz.
5. Using SCP, transfer the tar file to your VM.
6. At a command prompt, enter the following command to decompress the tar file: [root@smc ~]# tar xzvf se7310-Linux-i386-ni.tar.gz
7. Install the EMC Solutions Enabler by entering the following command: [root@smc ~]# ./se7310_install.sh -install]
8. Verify that the emc/symcli bin folder is in the Linux path, with this directory structure: <symcli path>/bin. An example is: /opt/emc/symcli/bin.
9. To connect to the VMAX device from Cisco UCS Director, you must update the PATH variable with the SYMCLI binary dir by updating the .bashrc file for the user that logs in to VMAX.
DETAILED STEPS
Step 1 | Create the base
Linux image for the VM you will use.
For the base Linux image, you can use an SMC or SPA servers that run CentOS, version 5.7 x86, or x86_64. For an SMC server, allow 20 GB of space. For an SPA server, allow at least 120 GB. | ||
Step 2 | Assign a few gatekeepers as RDMs. | ||
Step 3 | Reboot the Linux VM. | ||
Step 4 | From the EMC
Powerlink site, download the EMC Solutions Enabler package for Linux and the
Services Management Application System (SMAS) package
se7310-Linux-i386-ni.tar.gz.
Use MD5 Checksum 9809ac14ed8bfcc19789d7d5671d6015. | ||
Step 5 | Using SCP, transfer the tar file to your VM. | ||
Step 6 | At a command prompt, enter the following command to decompress the tar file: [root@smc ~]# tar xzvf se7310-Linux-i386-ni.tar.gz | ||
Step 7 | Install the EMC Solutions Enabler by entering the following command: [root@smc ~]# ./se7310_install.sh -install] | ||
Step 8 | Verify that the emc/symcli bin folder is in the Linux path, with this directory structure: <symcli path>/bin. An example is: /opt/emc/symcli/bin. | ||
Step 9 | To connect to
the VMAX device from
Cisco UCS Director, you must update the PATH variable with the SYMCLI binary dir
by updating the .bashrc file for the user that logs in to VMAX.
|
Adding an EMC VMAX Account
You must install an EMC VMAX Solutions Enabler on a Linux or Windows Virtual Machine (VM).
![]() Note | If you have Solutions Enabler 8.0 installed, when adding an EMC VMAX account, all Symmetrix device names are padded with a zero. This may cause issues with rollback operations for tasks that were executed against an older version of Solutions Enabler. |
Cisco UCS Director tests the connection to the EMC Symmetrix VMAX or VMAX3 storage system. If that test is successful, it adds the VMAX account and discovers all infrastructure elements in the storage system that are associated with that account. This discovery process and inventory collection cycle takes few minutes to complete.
VMAX Management
In a Cisco UCS Director EMC VMAX account, you manage the following pools, groups, devices, and views:
-
Thin pools—Create or delete, expand, bind or unbind, and view details
-
Devices—data devices, thin devices, regular devices, BCV devices, and meta devices
-
Initiator groups—Create or delete, rename, add or remove initiator, replace initiator, set override flags, and view details
-
Storage groups—Create or delete, rename, add or remove device, associate/disassociate FAST policy, and view details

Fully Automated Storage Tiering
Fully Automated Storage Tiering (FAST) automatically moves data between storage tiers. For example, FAST can do the following:
-
Move very active data to high-performance storage tiers
-
Move inactive data to low-cost, high-capacity storage tiers
FAST policies dictate how the performance and cost are optimized for the associated storage tier while the automation of FAST means that your storage system has no added management constraints compared with slower and more expensive systems. A FAST system always monitors and identifies the current activity levels of your data and moves the active data and inactive data to the most appropriate storage tier (according to your policies).
FAST Policies
A FAST policy is a set of tier usage rules that you can apply to your storage groups. A FAST policy can include up to three tiers and assigns an upper usage limit for each tier. The usage limit specifies the maximum percentage of the storage group that the FAST controller can allocate to a particular tier. Policy settings allow you to control and manage automated activity.

Masking Views
VMAX designates three types of auto-provisioning groups: storage groups, port groups, and initiator groups. These three groups work together as a masking view.
The masking view ensures that the target initiators in an initiator group can access the target storage resources in a storage group by means of the target ports in a port group.
Masking views are also useful for making changes to how the storage is presented. Changes to groups that belong to a masking view, such as adding a device or port, are automatically reflected in the masking view.
Creating a Masking View
You must create a storage group, initiator group, host LUN, and port group.
You must also attach devices to the storage group.

VMAX Properties File
You can configure certain parameters in the VMAX properties file (vmax.properties), which is located in the /opt/infra/inframgr folder.
Action or Task Retry Parameters
By default, the VMAX properties file is configured to automatically resubmit a service request or action if a workflow fails because too many tasks or actions are being executed simultaneously. This configuration reduces the level of user intervention required in this scenario.
Parameter |
Description |
Default Value |
||
---|---|---|---|---|
emc.vmax.retryMessages |
The error message that displays if a workflow fails because too many tasks or actions are being executed simultaneously. If this error message is captured for a task or action, that task or action is automatically re-executed. |
Default Error Message: The SYMAPI database file is already locked by another process
|
||
emc.vmax.maxIterationCount |
The maximum number of attempts to be made if the VMAX response contains the message specified in the retryMessages property. |
Default value: 20 |
||
emc.vmax.sleepTime |
The time (in ms) that the retry operation waits before it connects to the VMAX device to execute the command. |
Default value: 30000 ms (30 sec) |
VMAX Sym Device Inventory Collection
By default, Cisco UCS Director collects the sym device inventory for every 500 devices. You can change this default in the VMAX properties file.
Parameter |
Description |
Default Value |
---|---|---|
emc.vmax.inventory.symdev.count |
The number of VMAX devices for which inventory is collected. This parameter can be useful to reduce the inventory time required if the VMAX system has a large number of sym devices. |
Default value: 500 |
