EMC Symmetrix Enginuity Operating Environment

December 19th, 2008 8 comments

TO SUBSCRIBE TO STORAGENERVE BLOG

The Clariion Environment is governed by Flare Code and the Symmetrix / DMX by Enginuity Code. The Enginuity Code was developed internally at EMC and so far to my knowledge not outsourced anywhere for development purposes.

EMC Engineering is the crown of EMC, inventing new technology and pushing the envelope in terms of defining future products, technologies and markets.

Unlike the Clariion Flare Code that is customer upgradeable, the code on EMC Symmetrix / DMX is upgraded through EMC only. This code sits on the Service Processor but also gets loaded on all the Directors during installation and upgrades. On these Directors is also loaded the BIN FILE (Configuration of the Symmetrix) along with the Emulation code. The initial Enginuity code load and BIN FILE setup is performed when the customer first purchases the machine and is customized based on their SAN environment.  

As new Enginuity code releases hit market, customers can get the upgrades from EMC. It is very normal for customers to go through multiple code upgrades during the 3 to 5 year life cycle of these machines.

The service processor houses the code, but the Symmetrix / DMX can be rebooted or can be fully functional without the Service processor present. The Service processor will allow an EMC trained and qualified engineer to perform diagnostics and enable the call home feature for proactive fixes and failures.

For any host related configurations changes, the presence of this service processor including EMC’s Symmwin Software is absolutely necessary. Without the presence of above it becomes impossible to obtain configuration locks on the machine through ECC or Symcli, restricting customer BIN FILE Changes for reconfiguration.

Enginuity Code level break down are based on the Family of machines.

Typically 50XX versions are limited to Symm 3.0 Models (3100/5100, 3200/5200, 3500/5500). 

The 37xx versions are limited to Symm 2.5 Models (4200,4400, 4800)

The code levels 5265, 5266, 5267 are limited to Symm 4.0 (3330/5300, 3400/5430, 3700/5700) and Symm 4.8 family (3630/5630, 3830/5830, 3930/5930) of machines.

For Symm 5.0 and 5.5 the Enginuity code versions are 5567 and 5568. The last code version for the Symm 5.0 and 5.5 is 5568.68.28. There will be no code upgrades for the Symmetrix after this version.

Going into the DMX1 & DMX2 (DMX800, DMX1000, DMX2000, DMX3000), code levels 5669, 5670 and 5671 are the major family Enginuity Code levels. For the DMX3 and DMX4 code levels 5771, 5772 and 5773 are the major releases.

The latest version 5671.75.75 is the last known version for the DMX1 and DMX2 family of machines.

 

The guidelines for Enginuity Code level breakdowns is as follows.

Example 5671.75.75 (Please see the color coded system below)

 

First Two digits

50=Symm 3.0

52=Symm 4.0, 4.8

55=Symm 5.0, 5.5

56 = DMX1/DMX2

57 = DMX3/DMX4

 

The next two digits are

67, 68 = Microcode Family, Major Symmetrix Releases for Symm 5.0/Symm 5.5

69, 70, 71 = Microcode Family, Major Symmetrix-DMX Releases for DMX1/DMX2

71, 72, 73 = Microcode Family, Major Symmetrix-DMX Releases for DMX3/DMX4

 

The next two digits are

Emulation Number designated as EE 

 

The last two digits are

Field Release level Service Processor Code Level (Symmwin Version)

 

The version of the Enginuity code will define what functionality and features the Symmetrix / DMX will have for that generation. As the hardware gets better and faster, the Enginuity Code has to improve and add features to perform along with it. 

Clariion CX, CX3, CX4 – Serial Number of Clariion CX3-20, CX3-40, CX3-80

December 16th, 2008 1 comment


For CX3 series model 20 and model 40

The storage-system serial number (TLA S/N number) is located behind the storage processor enclosure’s front bezel. To remove the front bezel, push the two buttons on the front of the bezel and pull the bezel toward you. The serial number is on a vertical blue label on the left side of the chassis.

For CX3 series model 80

The storage-system serial number (TLA S/N number) is located behind the front bezel. To remove the front bezel, push the two buttons on the front of the bezel and pull the bezel toward you. The serial number is on a horizontal blue label on the left side of the chassis.

Clariion CX, CX3, CX4 – Navisphere Storage System Initialization Utility

December 16th, 2008 No comments

For CX-series storage systems, use the utility to discover storage systems, and set network parameters (IP address, subnet mask, and default gateway). An authorized service provider must install and run the Initialization Utility.

For AX-series storage systems, use the utility to discover storage systems, set network parameters (IP address, subnet mask, and default gateway), and create management user accounts.

For AX150 and CX3-series iSCSI storage systems, use the utility to set network parameters for the storage system’s iSCSI data ports.

You must initialize the storage system in order to register the server HBAs with the storage system and have access to the storage system’s data.

Note: The Navisphere Initialization Utility runs on servers attached to CX3-series, CX700, CX500-series, CX300-series, and AX-series storage systems. CX3-series systems must be running FLARE OE 03.22.xxx.5.yyy or later. CX700, CX500-series, CX300-series, and AX100-series systems must be running FLARE OE 02.16.xxx.5.yyy or later. AX150-series systems must be running FLARE 02.20.xxx.5.yyy or later.

Clariion CX, CX3, CX4 – Navisphere Host Agent

December 16th, 2008 No comments

The Host Agent registers the server’s HBA (host bus adapter) with the attached storage system when the Agent service starts. This action sends the initiator records for each HBA to the storage system. Initiator records are used to control access to storage-system data. The Agent can then retrieve information from the storage system automatically at startup or when requested by Manager or CLI. The Host Agent can also:

· Send drive mapping information to the attached CLARiiON storage systems.

· Monitor storage-system events and can notify personnel by email, page, or modem when any designated event occurs.

· Retrieve LUN WWN (world wide name) and capacity information from Symmetrix storage systems.

Note: The Host Agent runs on servers attached to CX-series and AX-series storage systems that have been upgraded to Navisphere Manager, that is, that have the Navisphere Manager enabler installed.
