How-To Generate SP Collect Data from Unisphere

December 22, 2011

Many times you may be asked to provide “SP Collects” for your EMC Array.  This may be for EMC Support or for your VAR, who may need to see how your existing array is configured.  Either way SP Collect data is very useful and relatively easy to generate.  With the release of Unisphere for EMC Clariion, Celerra and VNX the menus and processes have changed just a little.  Below you will see step by step instructions on how to generate these files from the new Unisphere interface.

         Login to the Unisphere console

         Select the array you want to collect data from

         Click on the “System” tab, then click on “Generate Diagnostic Flies – SPA” under the “Diagnostic Files” section on the right.

          Click YES to generate the SP Collect Data for SPA

         Click on “OK” to confirm the success of the process

         Now click on “Generate Diagnostic Files – SPB” under the “Diagnostic Files” section on the right.

         Click YES to generate the SP Collect Data for SPB

         Click on “OK” to confirm the success of the process

         Click on “Get Diagnostic Files – SPA

         The SP A – File Transfer Manager Window will appear.

  • 1st – sort the files by date with the most recent date at the top by clicking the top of the “Date” column.
  • 2nd – Highlight the “APMxxxxxx.zip” file.  (Depending on your array – your file may not start with “APM” but with a different set of letter.  Regardless, the rest of the file name will be followed by a series of numbers_SPA_date_time)
  • 3rd – Select your destination directory where you want the file saved to.  (Use something easy to find like c:\)
  • 4th – Click the “Transfer” button below the list of files

         Click on YES to confirm you want to transfer the file.

 

         In the “Transfer Status” window – look and wait for the file transfer to report successful. (This may take a minute or so)  Once the transfer is successful click OK.

         Click on “Get Diagnostic Files – SPB

 

         The SP B – File Transfer Manager Window will appear.

  • 1st – sort the files by date with the most recent date at the top by clicking the top of the “Date” column.
  • 2nd – Highlight the “APMxxxxxx.zip” file.  (Depending on your array – your file may not start with “APM” but with a different set of letter.  Regardless, the rest of the file name will be followed by a series of numbers_SPB_date_time)
  • 3rd – Select your destination directory where you want the file saved to.  (Use something easy to find like c:\)
  • 4th – Click the “Transfer” button below the list of files

         Click on YES to confirm you want to transfer the file.

 

         In the “Transfer Status” window – look and wait for the file transfer to report successful. (This may take a minute or so)  Once the transfer is successful click OK.

         Open up Windows Explorer or whatever file manager you use and go to the destination directory where you downloaded the files to.  Verify the SPA and SPB .zip files are there.

         Send those files to your VAR or EMC technical consultant/contact.

EMC Celerra CIFS Share Management – Two Ways To Skin A Cat

June 18, 2010

First off, the “Skin a cat” thing is just a figure of speech so if you’re a cat lover don’t report me to PETA.  I would never do something like that…….well…….unless the damn thing bit me or really pissed me off, then all bets are off!  Actually I’m sure this will make good FUD for the competitors.  Now on top of all the EMC stories we hear like, “EMC kills puppies and kicks old ladies down the stairs” they can add “they skin cats too!”.  Barbarians!

Anyway on to the EMC stuff.  This week I’ve had to do a few demo’s showing some basic functionalities of the Celerra platform.  The one thing most people do with a NAS solution is to manager their Windows CIFS shares.  So to demonstrate how easy this process is I created a short Youtube video which illustrates how do this both using Celerra Manager and Windows MMC.  Check it out below.

EMC 146GB Drives Get Shanked!

February 7, 2010

It’s all over for the 146GB drives.  Last week EMC announced that the 146GB fibre channel disk drives will no longer be available for new Clariion and Celerra platforms.  I don’t see this as a huge deal to most customers but for some very specific applications the drives were very useful. 

Some databases that we run across have very high I/O requirements but really do not require much disk capacity.  For applications like these where you many need 20+ spindles to get the performance you need the 146GB drives were perfect because of their price point.  The other situation where the 146GB drives were handy was for the Vault on the Clariion and Celerra platforms.  As a general practice you don’t want to use the remaining space on the Vault drives for anything with high I/O requirement as to not affect the performance of the array.  For many clients they would not put anything on the remaining space on the Vault.  So why use 300GB of 450GB drives for the Vaults 4+1 RAID5 when you really only need 300GB – the 146s were perfect for this.

On the flip side of this argument, drives prices over the last year have come down significantly so having to use 300GB drives really doesn’t cause a huge financial impact on new arrays.  The fact is that for most of the clients we’ve worked with, 146GB drives were just too small for the majority of applications.  Let’s face it; the trend of data growth is going upwards steeply.  Most reports and studies I’ve seen show industry average data growth anywhere from 30 – 50% per year.  With that kind of growth smaller capacity drives will continue to become “legacy hardware”.
