Q: Can I use LTFS with tape libraries? A: From v3.4, the Windows version of StoreOpen Software does offer support for HPE’s range of tape libraries; however the Linux & Mac versions do not provide such support. Tape drives located in tape libraries can be used, but there is no support for listing or changing cartridges. It may be possible to use other third party utilities for such purposes but that is beyond the scope of StoreOpen Software and HPE is unable to support customers experimenting with such configurations.
2022/11/09時点での最新は、 HP StoreOpen Software : ver3.5.0(2022/01/24) LTO-9対応/LTFS 2.4対応 また、ソースコードもダウンロードできる。
ソフトウェア入手は上記の公式ページの「Software」タブから行う。 ソースコードについては、LTFS Open Source Filesから。どちらも2019年から更新されていない。
2022/11/09時点での最新は下記 Linux/Mac : ver2.4.0.2(2019/03) LTO-8/LTFS2.4対応 Windows Model Bドライブ向け: ver3.0(2016/04) LTO-6以降という曖昧な記述のみ Windows Model Cドライブ向け: ver2.4.0.2(2018/04) LTO-8/LTFS2.4対応。おそらくLinux/Mac向けと同じベース
LTFSを紹介するページはあるものの、LTFSを利用するソフトウェアに関するページが見当たらない。 「Spectra libraries are compatible with LTFS software and hardware solutions from a range of providers.」とあるので自社では直接提供していないようだ。
IBM LTFS 2.2.0.2とHP LTFS 2.2.1を組み合わせ、Oracle/StorageTek用の設定を入れたもの。 Oracle LTOドライブ,IBM LTOドライブ,HP LTOドライブに対応している。
「LTFS For Dummies」という51ページのPDFを公開しているのが興味深い。 ??? For Dummiesは、アメリカで販売されているいろんな分野の初心者向け書籍シリーズ。「ダミー人形向けの」→「バカでも分かる」というものなんだけど・・・このLFS for Dummies、解説具合が微妙過ぎるなぁ・・・
注:この記事での事象はsamba 4で使用していた証明書の期限切れが原因でした。 「LDAP Error: Strong authentication is required Details」もしくは「「Unable to connect to NetLogon service on」」というエラーがでる場合については別途「ONTAP 9.5でsambaドメインに参加できない & ONTAP 9.7で失敗」という記事にしています。
