After a fresh install of SSIM 4.8.1 there are tablespace and index errors in simdbmu.log.
The Table or Index in the error will vary, but below is an example:
2015-08-22 19:44:27,598 201304143 [DBMU-1] WARN com.symantec.sim.simdb.job.BaseHealthJob - incident - Caught exception during doQuickRunstats for table SYMCMGMT.SYMC_SIM_POLICY
com.symantec.sim.simdb.utils.sql.SimDbTableOrIndexDoesNotExistException: Table or index does not exist: CallableStatementCallback; nested exception is com.ibm.db2.jcc.am.SqlException: DB2 SQL Error: SQLCODE=-2306, SQLSTATE= , SQLERRMC=SYMCMGMT.SYMC_SIM_POLICY, DRIVER=3.63.75
The appliance SSIM is being installed to is a Single Disk install but also has a device showing during boot which udev is identifying as a second disk.
Because of this the installer thinks it is a Two Disk install and there for tries to setup DB2 on the second disk but fails.
Ensure no external storage devices are connected via USB such as a "Thumb Drive" or External Hard Drive.
For the following you must have console access to the hardware system or a Remote Console capability.
After confirming none of the above situations exist or they are removed/disabled, install SSIM.
