How to delete a HP Data Protector StoreOnce Software Deduplication store

In one of my earlier blogposts, I mentioned what you could do when you are confronted with a “corrupted” HP Data Protector software StoreOnce store. Today, we decided to delete the deduplication store to free up the diskspace.

Before a “HP Data Protector StoreOnce Software Deduplication Store” can be deleted, the media retained within needs to be exported. Please note, deleting the store in DataProtector does not mean the Store is deleted in StoreOnceSoftware.

The deletion required a set of steps to be executed. The plan of approach we followed, can be found below.

Data Protector report the following error message when executing a barcode scan: “Bad catalog access for message #193 in set 65″

Today we received the following error message in the Data Protector GUI when we performed a barcode scan on a physical tape library: “Bad catalog access for message #193 in set 65“. Yesterday I found some Data Protector foreign tapes which we tried to format, logically we thought these were the root cause of this error message. After exporting them out of the library, we noticed the error stayed.

Eventually we found out this error was caused by a miscommunication between the Cell Manager and the client which has the HP Data Protector GUI installed. These error messages can appear when there is a discrepancy in the Data Protector versions installed.

In our situation, we had the HP Data Protector Cell Manager running on version 9.04 and we were using a Data Protector Console of version 9.02. After patching the console, the error disappeared and we were able to successfully manage the cell again.

Windows 10 Start Menu and Modern Apps do not open

Out of a sudden, the start menu on my Windows 10 computer didn’t respond anymore. I noticed I was unable to open the calendar anymore as well. It caught my eye the system installed a patch (KB3093266) yesterday and decided to remove it first before continuing with my troubleshooting. After removing the patch and rebooting the system, the start menu was still not behaving as it should.

I decided to boot the computer in “safe mode” (msconfig > boot) and check if the start menu works in safe mode, which was not the case. I have to admit, it was a long shot… but you never know!

Eventually after some Google magic I found the solution on the Microsoft forums. Open a PowerShell with administrative privileges and execute the following command: “Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}“.

The execution can take some time (up to 2 minutes). Any errors listed in the powershell command can be ignored. Upon completion the Start Menu and the Modern Apps open successfully again.

Disk presentation is unsuccesful even with succesful Fabric Login Process (FLOGI)

So recently I encountered a very weird phenomenon at one of my customers and we had a very hard time to determine the root cause of the issue.
My customer buys his servers each time in a set of 12 (one rack). All servers are equipped with a dual-port fiberchannel Host Bus Adapter (HBA). Each port is connected to a different fabric (TOP & BOT fabric).

One of the racks freshly installed a few weeks before the maintenance weekend when we performed a storage-, SAN switch & server upgrade was causing a whole bunch of issues. The fact is that all switches are in a healthy state, no errors are visible in the errorlog and all ports have succesfully performed a Fabric Login Process (FLOGI).

Our customers uses HP Proliant DLxxx G7 servers with a combination of QLogic and Emulex fiberchannel cards. The fiberchannel switches are HP-branded: HP Brocade 8/40 SAN switch.

In a first case, we verified the port configuration:

  1. Fix speed? Yes, 8G.
  2. Fillword? Configured with mode 3 (aa-then-ia: attempts hardware arbff-arbff (mode 1) first. If the attempt fails to go into active state, this command executes software idle-arb (mode 2). Mode 3 is the preferable to modes 1 and 2 as it captures more cases.)

and ofcourse the port statistics (and in more detail, the port errors). Here I came to the conclusion the numbers where very static. Wich means the port is online in the fabric, and as no errors are filling up I came to the conclusion the port was not being used in the fabric even it was zoned out with a storage array and a disk has been presented.

CommVault Oracle backup fails with error code 62:342

Out-of-the-blue we encountered that two of our Oracle databases started failing with the error code “62:342″ and description “Encountered an I/O error while performing the operation”. The odd thing is that we have more than 15 databases on the server and only two of them were having the issue.

Important to note is the fact that the server itself is a MediaAgent, which means the server has access to a shared tape device (in our case a VTL). The VTL itself is shared with approximately 90 MediaAgents and the storage policy used for database backup is associated with more than 250 databases. And… only 2 were failing…

Abort an unresponsive Data Protector job

Sometimes aborting a job by using the Data Protector Manager Console does not succeed.
In those situation, follow this procedure:

  • Go to the Data Protector Manager console > Monitor > Session-Id and take a not of the start time.
    [Normal] From: BSM@CellManager.lab.local “FILE_DAILY” Time: 5/23/2013 4:15:05 AM
    Backup session 2013/05/23-13 started.
  • Open a PowerShell Window and execute the following command: “get-process b* | sort-object StartTime | format-table Name,Id,StartTime”
    Name Id StartTime
    —- — ———
    bsm 8532 18/05/2013 4:15:07
    bsm 8996 19/05/2013 5:15:05
    bsm 11672 23/05/2013 4:15:05
  • Execute the following command to kill the process: “stop-process 8532“.

Execute the command “omnistat” or “get-process b* | sort-object StartTime | format-table Name,Id,StartTime” to verify the operation. Restart the Data Protector Management console to clear the monitor in the GUI.

Uninstall Command View + manual cleanup of the registry and files

Last weekend, I performed a firmware and management software upgrade and I encountered this one. It took me some hours of troubleshooting, logfile checks, uninstall-clean-install scenario’s. Eventually I decided to open a case at HP Support to get this resolved.

In one of the logfiles they noticed this logentry:
mrt 24, 2013 7:36:58 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: A web application created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@158a9b]) and a value of type [org.dom4j.DocumentFactory] (value [org.dom4j.DocumentFactory@3f02ae]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.

They recommended me to perform an uninstall and entire cleanup scenario to solve this. Below is the procedure provided by HP Support.
