SRM: Three updates, EMC / LSI / Hitachi SRA

· ·

Just noticed three SRAs were updated. Might be worth checking out:

  1. EMC Symmetrix Storage Replication Adapter
    Version 2.0.0.21 | Released 04/20/2009
    Fixed : SRDF Adapter for VMWARE Site Recovery Manager (SRM) times out while trying to enumerate LUNs from a local Symmetrix array.
  2. LSI Storage Replication Adapter
    Version 1.00.30.12| Released 04/01/2009
  3. Hitachi Storage Replication Adapter 2
    Version 1.0.8| Released 03/24/2009

I added one of the fixes which is included with the EMC Symmetrix SRA cause I blogged about it a couple of months ago and I’m glad this has been solved.

SRM: Automatically rename your datastore back

· ·

When doing a failover with SRM your VMFS Datastores get labeled with a “snap-xxxxxxx-name” because they’ve been resignatured. Mike Laverick gave this tip on the VMTN forum which enables you to automatically rename your datastores to it’s original name again:

Edit the vmware-dr.xml file in the C:\Program Files\Site Recovery Manager\Config directory and look for a line that reads:

  • <fixRecoveredDatastoreNames>false</fixRecoveredDatastoreNames>

Change it to:

  • <fixRecoveredDatastoreNames>true</fixRecoveredDatastoreNames>

SRM 1.0 Update 1, patch 3

· ·

I just noticed this SRM update, it’s just a small patch but looking at the problems it corrects it might be beneficial to upgrade!

Site Recovery Manager 1.0 Update 1 Patch 3 Latest Release Version: 1.0.1.2587 | 04/09/09 | 154949

This patch corrects the following problems:

  • a problem that prevents protected virtual machines from following recommended Distributed Resource Scheduler (DRS) settings when recovering to more than one DRS cluster.
  • a problem observed at sites that support more than seven ESX hosts. If you refresh inventory mappings when connected to such a site, the display becomes unresponsive for up to ten minutes.
  • a problem that could prevent SRM from computing LUN consistency groups correctly when one or more of the LUNs in the consistency group did not host any virtual machines.
  • a problem that could cause the client user interface to become unresponsive when creating protection groups with over 300 members several problems that could cause SRM to log an error rmessage vim.fault.AlreadyExists when recomputing datastore groups.
  • a problem that could cause SRM to log an Assert Failed: “ok” @ src/san/consistencyGroupValidator.cpp:64 error when two different datastores match a single replicated device returned by the SRA.
  • a problem that could cause SRM to remove static iSCSI targets with non-test LUNs during test recovery several problems that degrade the performance of inventory mapping.

SRM install log files

· ·

I was rebuilding my lab this evening and ran into some weird problem during the installation. I wanted to debug it but couldn’t find the log files. After a quick search on the VMTN forum I found the following, which creates a log file called “SRMinstall-log.txt”:

VMware-srm-1.0.1-128004.exe /V"/lve SRMinstall-log.txt"

I know it’s a weird looking format, but it actualy works! Of course if you’re using a different version you should change the .exe accordingly. Thanks Lee aka Smoggy.

  • Frees up enough storage to host 50 times the current volume of photos on Facebook
  • Offers 4 times more memory per virtual machine
  • Handles 8,900 transactions per second in a virtual machine
  • Handles 3 times eBay’s daily traffic on a single server
  • Supports 4 times more operating systems than the competition
