Hi, We have sold/implemented a number of IBM NVMe based storage solutions to our customers over the last few months, mostly V7000 (before FS rebranding) and FS9150s. So far, performance improvements over their old storage are great, and native data reduction ratios are as we expected them to be (when ...

Hi, Totally agree with this! There is a resurgence in tape due to everyone desperately trying to implement air-gapped copies of their backup data for cyber-resiliency purposes. And tape still has the lowest cost per TB for long term data retention. The LTO roadmap goes up to at least generation 12, which ...

Hi Prem, Are all of your volume groups varied on, and all disks marked available? It may also be useful to check the db2diag.log for and database related errors.

Hi Prem, This can happen when you try to access dsmc using a non-root user. Who are you trying to run dsmc as? If you are running Linux or UNIX you could try the following to check that all the library symbolic links are in place: ldd $(which dsmc) Regards Darren ------------------------------ Darren ...

Hi Prem, I copy and pasted your SQL query into dsmadmc session on an 8.1.6 and it worked fine for me. Protect: PROTECT01>select * from events where scheduled_start>current_timestamp-24 hours and node_name in ('A', 'B', 'C') ANR2034E SELECT: No match found using this criteria. Regards Darren -- ...

Hi Prem, From within the OC, go to the Reports section and then create a new report using custom SQL queries. You can then enter multiple SQL queries to include in your report. If you wish to know backup events from the last 24 hours for specific nodes, you could use a query like: select * from events ...

Hi Prem, Has someone tried to start this instance using a different user account other than the instance owner, e.g. root? Can you check by running a "ps -e" command and look for any dsmserv processes. If there are any, check which user owns the process. Then log in as that user and halt the ism instance. ...

Hi Prem, The easiest way to do this is to use the BA GUI client, select the file you wish to restore and select the option to show active & inactive versions. The CLI option, can take a long time to run due to the amount of data in the backup table. You can use the "inactive" option: e.g. dsmc query ...

Hi Prem, Do you have a dsmserv.opt file that is located in the non-default location? Just wondering if your server is coming up using the wrong opt file, hence the issue with the admin ports.

Hi Prem, Seems odd that you have 2 library managers and 1 library client? Does each library manager manage a dedicated library partition? Could you check the library and drive paths (q path) on each TSM server, managers and clients. And also do a 'q drive' to check the drive status. Cheers Darren -- ...

Hi Prem, I think the problem here is actually with start time in your SQL query. You are looking for events where the start time is in the future.

Hi Carlos, Is your cloud storage on-premise or off-premise? Your can use traditional node replication techniques to replicate your cloud container pool to another Spectrum Protect server, its just the PROTECT STGPOOL functionality that you cannot use. We have Cloud Object Storage spread over three sites, ...

Hi Prem, You could use a third party monitoring/reporting tool such a Servergraph, which can report on external schedulers. Or, if you know the name of the scripts that are being called, you could create queries against the sessions table to see when the scripts start and finish and monitor their return ...

Hi, Totally agree with this. Many people consider tape to be a dying technology, when in fact it is a growing market. Most unstructured data that people store in the cloud (photos, music, etc..) is actually stored on tape media. IBM has a roadmap for tape that stretches over 10 years into the future, ...

Hi Prem, As the SYSTEMSTATE is a special object, as far as TSM is concerned, is cannot be backed up using any schedule that is not a full incremental backup. Therefore, I think you should use two schedules: backup the SYSTEMSTATE using the action=backup backup your data drives using action=inc ...

Hi Katherine, I hadn't heard of this new feature, but after you mentioned it I started to think about it... and personally, I can't think of a reason why I would want to use it. Thin provisioning of virtual disks that are mapped to host systems is completely understandable and very common, but thin ...

Hi, A few things to check... Are you using the traditional TSM scheduler or the Client Acceptor Daemon (CAD)? Is the scheduler/CAD service running and defined to auto start using a system account? If you restart the scheduler/CAD, do you see connectivity messages in the dsmsched.log with details ...

Hi, There are probably a few way to accomplish this... You could create additional data movers on the vStorage backup server, with their own dsm.opt files that point to a new management class with the appropriate data retention settings. The new data movers would then have their own backup schedules ...

Hi, Try the following command to report on all activity in the last 24 hours, in GB. SELECT activity, cast(float(sum(bytes))/1024/1024/1024 as dec(8,2)) as "GB" FROM summary WHERE activity<>'TAPE MOUNT' AND activity<>'EXPIRATION' AND start_time >('2011-09-21 00:00:00') AND start_time ...
