It depends on how your system is set up. Ask your storage mangement people if there are backups of the data or volumes. And tell your boss you will be more careful the next time (if there is a next time). |

I track this using SMF data, looking at when the catalog entry "delete" activity for the files. |

a very good tool to analyze smf record is the free:
DAF dataset Audit Facility, by Mke Cleary
File # 094 DAF from Mike Cleary - Dataset Audit Facility NEW
http://www.cbttape.org/ftp/cbt/CBT094.zip
but better search for the latest release |

HRECOVER is to recover a data set from a backup version or restore a data set from a dump copy ... |

You can use HRECOVER if
a) HSM is installed and active
b) HSM has a valid backup version to recover from
As suggested earlier, talk to your storage people as there may be backups / dumps of the volumes that you do not know about |

Expat,
I had sent a mail to storage people.
Could you please let me know what is HSM? and how to check whether its activated or not? |

Do a 3.4 on your datasets, and if any of them show as MIGRAT or MIGRAT2 type HRECALL on the line of one of those datasets.
If HSM is installed it will recall the dataset, else it will give an error message |

Hierarchical Storage Management (HSM) is a data storage technique which automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as hard disk drive arrays, are more expensive (per byte stored) than slower devices, such as optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed (this is when one issue HRECALL, however at some sites you might have this command mapped to some other smaller line command; at my shop I use 'HR').
If HSM is installed, Data files which are frequently used (and) are stored on disk drives, but were not used for a certain period of time (which would vary site to site) are eventually migrated to tape. |

Hi Guys,
As I was interested in this topic, I searched related topics in this forum and links and came to know about the utility IFASMFDP. I tried it on my platform but it's not working. I could not find any file starting with sys1.man*
Is the name of file platform dependent? How do I get to know it ?

Whoa back ..... these are usually the SMF recording datasets, but may vary in name from site to site. Please do not attempt to use these datasets.
IFASMFDP will dump the inactive SMF datasets and if you vary the expected output names, you will cause gaps in the SMF data, which as it is used for things like catalog recoveries, billing, performance and capacity planning does not seem like a good idea to me.
Have a word with your storage people / sysprogs / capacity planners as to the names of the DUMPED SMF data and play with that data as input into IFASMFDP. You can use it to read dumped data and select only the record types that you are interested in, but there again you can do that and more using DFSORT. |
