For convenience, a wrapper script tungsten_find_seqno is also available. In all the examples below, simply replace tpm find-seqno with tungsten_find_seqno or vice versa.
The tpm find-seqno assists with locating event information in the THL and producing a dsctl set command as output.
The tpm find-seqno command performs the following steps:
Get the Replicator sequence number to search for from the CLI and validate
Validate paths and commands
Load all available service names and validate any specified service against that list
Check if this Replicator is in the Primary role
Locate the supplied seqno in the available THL
Parse the THL found, if any
Generate the dsctl command and display
