9710 (StorageTek) Addendum for NonStop Servers

Addendum to the StorageTek™ 9710 for the Tandem Environment
The 5155/5159 Digital Linear Tape CRE and NonStop Kernel
9-42
For the 5155, 5159, 5150 or 5151 tape drives using the MFC, the
BLOCKSIZE value can vary from 4 through 28 in increments of 4.
For drives using 3216 controllers, BLOCKSIZE can be as large as
52. The default BLOCKSIZE is 8 (8192 bytes). When using larger
block sizes, make sure all tape drives and systems that will read the
tape (supporting the BLOCKSIZE specified).
Before using BLOCKSIZE values larger than 28, consider this:
• Only Cyclone and Himalaya K10000 and K20000 systems with
3216 tape controllers support BLOCKSIZE values larger than
28.
• The MFC does not support BLOCKSIZE values larger than 28.
• A tape that was backed up with a BLOCKSIZE larger than 28
can be restored only on a system using a D30 or later version of
RESTORE on a tape drive that supports the larger block
transfers.
• Expand networks do not support BLOCKSIZE values larger
than 28.
For more information about the BLOCKSIZE option, refer to the
Guardian Disk and Tape Utilities Reference Manual.
