ha_related_suse_tids(7)
πΈ NAME πΈ
okay so welcome to ha_related_suse_tids(7) β that's the manual page name, and it comes to you from ClusterTools2, section 7 of your friendly neighbourhood man pages. it's literally a hand-picked selection of SUSE Technical Information Documents, all related to high availability π
β¨ DESCRIPTION β¨
bestie. this whole page is a curated reading list. it lists SUSE Technical Information Documents (TIDs) that are all about high availability topics. think of it as the pre-approved stack of docs you go through when a cluster is being dramatic π
the documents mentioned here β and others too β are stored with the SUSE Knowledgebase at https://www.suse.com/support/kb/ . that's the place. go there. live there. π¦
π§ useful keywords for searching
when you're hunting in the Knowledgebase, these are the keywords that actually pull results:
<number_of_TID>openaiscorosyncpacemakerhaesle-hasbdstonithfencingocfsaprearsupportconfigmpiomultipathiscsi
π«Ά product to select
the Product filter is usually one of these:
<empty_string>SUSE Linux Enterprise High Availability ExtensionSUSE Linux Enterprise ServerSUSE Linux Enterprise Server for SAP Applications
no cap: the empty string is a real choice here, so don't panic if you see it in the list π
π EXAMPLES π
here's the actual haul, grouped exactly like the original does it. the number in the parens is the TID β drop it into the Knowledgebase search and you're there β
