Choice 2 - Protect the application by converting the file to Guardian Format 1
using these steps:
FUP CREATE TEMP, FORMAT 1, TYPE U, ODDUNSTR, CODE 180, &
EXT (28,1400), MAXTENTS 749
FUP COPY MYFILE,TEMP
FUP PURGE MYFILE
FUP RENAME TEMP,MYFILE
°
Choice 3 - Protect the application by pre-creating the file as a Guardian Format
1 file and then appending data to the file.
For example:
Replace the command
cp myfile /G/disk/subvol/myfile
With the commands
gtacl -c 'FUP CREATE $disk.subvol.myfile, FORMAT 1,
TYPE U, ODDUNSTR,
CODE 180, EXT (28,1400), MAXTENTS 749'
cat myfile >> /G/disk/subvol/myfile
Migration
•
HP does not support transferring files larger than 2 GB to a system running a pre-
G06.29 RVU.
•
If you are currently running a pre-G06.24 RVU, consider migrating to the G06.28
RVU before migrating to G06.29 in order to facilitate fallback if fallback becomes
necessary.
•
Before migrating to G06.29, HP strongly recommends that users who are migrating
from G06.24 through G06.27 install the DP2 fallback SPR T9053G11^AQS in case
a fallback becomes necessary. T9053G11^AQS is on the G06.28 SUT. Installing
the T9053G11^AQS SPR requires a system load.
If the users choose not to install the DP2 SPR before migrating to G06.29 and they
later encounter a need for fallback, they must perform a system load on their prior
RVU. In addition, before using any OSS files, they must install and system-load to
the DP2 SPR. Falling back to the G06.23 or earlier RVUs is not supported.
For additional information on the SPR, see Fallback on page 2-10.
•
If you have a tape file with a mix of OSS files smaller than and larger than 2 GB
that need to be restored to a G06.23 to G06.28 file set that does not support files
