I am planning the upgrade of my TSM 3.7.0 servers (Solaris 2.7) to TSM 4.1.3.  
While reading the TSM4130S_Sun.README file I came across a disturbing 
pronouncement:  

<CUT>
**********************************************************************
* ACSLS not supported on Solaris 7 and 8                             *
**********************************************************************

Version 4.1.x (this version) of the Sun Tivoli Storage Manager does NOT support 
ACSLS on Solaris 7 and 8. 
</CUT>

I immediately called to get clarification of this statement.  I inferred this 
to mean that ACSLS running on Solaris 7 and 8 is not supported, which is no 
problem as I am running it on Solaris 2.6.  I spoke with a fine gentleman who 
explained that what they are trying to say is that TSM 4.1.x on Solaris 7 and 8 
does not support ACSLS.  PERIOD.  The reason he cited had to do with the ACSLS 
application being 32 bit code. He further explained that my options are to 
continue running TSM 3.7 (end of service announced for 10/31/01), or go back to 
Solaris 2.6.  I spoke to the shift manager and asked him to confirm this 
interpretation as surely this cannot be correct.  He concurred with the first 
gentleman.  He offered to reopened my PMR and directed it to the Development 
team.  He stated that if there is enough demand for it, they may develop the 
code for it.

I then followed up with STK support.  I asked if a 64 bit version was in 
development or planned and the answer is no, though ACSLS now supports Solaris 
7 and 8 (32 bit).  I am shocked.  We have a large and costly STK 9310 
implementation using 9840 tape drives.  Device support for STK 9310 libraries 
was one of the determining factors in our selection of TSM. I urge everyone who 
is as alarmed about this as I to contact Tivoli and encourage this.  I feel 
Tivoli is angling toward eliminating ACSLS libtypes entirely in favor of SCSI 
controlled libraries and SANs.  

Thanks,
