2431875 - HANA Upgrade Error Related to SSFS.DAT

Updating a HANA system via HDBLCM pre - revisions 85.05, 97.1, 101 will potentially result in a failure and errors in the hdbupd*.log:

INFO: nameserver_*.*.*.trc: [XXXXX]{-1}[-1/-1] [TIMESTAMP] e Crypto RootKeyStoreConsistencyProvider.cpp(00228) : SystemPKI SSFS
master key error: exception  1: no.301103 (Crypto/Ssfs/RootKeyAccess/RawAccess/RawRootKeyStoreReaderWriter.cpp:52)

"/usr/sap/<SID>/SYS/global/security/rsecssfs/data/SSFS_<SID>.DAT" cannot be opened in mode "rb": No such file or directory (errno = 2)

The following issue will be evident in the nameserver:

RawRootKeyStoreReader::read: SSFS-4218: Record with key "SYSTEM_PKI/PSE" not found in secure storage <-- SSFS-4215: Data file
"/usr/sap/<SID>/SYS/global/security/rsecssfs/data/SSFS_<SID>.DAT" exists, but does not contain the requested entry
