Were the 6 files originally one tarfile that was split?  If they are actually 6 tarfiles, why do you want to combine them?

 

Is the total over 2 GB and do you have largefiles enabled?

yes largefiles is enabled, the combined total is 9.8G, the other tar files that i combined was 4.5 and it worked with no problems..

Is the file size a multiple of 512 bytes?

Re: Size restriction on cat command

here is what i have to work with.

 

-rw-r--r--   1 root       sys        1835008000 Nov  3 10:20 1
-rw-r--r--   1 root       sys        1835008000 Nov  3 10:22 2
-rw-r--r--   1 root       sys        1835008000 Nov  3 10:24 3
-rw-r--r--   1 root       sys        1835008000 Nov  3 10:26 4
-rw-r--r--   1 root       sys        1835008000 Nov  3 10:30 5
-rw-r--r--   1 root       sys        648386560 Nov  3 10:32 6

 

 

i had to rename them to 1 thru 6, symantec had a 20+ charcter name to start with...when i am done with the command

 

cat 1 2 3 4 5 6 > NB_Appliance_N_2.6.0.1-1.tar

 

i end up with a tar file that looks like this

 

-rw-r--r--   1 root       sys        9823426560 Nov  3 12:32 NB_Appliance_N_2.6.0.1-1.tar

Looks like the right sum.  What errors does "tar -tvf NB_Appliance_N_2.6.0.1-1.tar" give?

 

>I had to rename them to 1 thru 6, symantec had a 20+ character name

 

Not sure why?  Just put the cat in a script or use wildcards.

Re: Size restriction on cat command

here is what happens when i extract the tar file.


x update.rpm.md5_checksum, 33 bytes, 1 tape blocks
x update.rpm.sha1_checksum, 81 bytes, 1 tape blocks
x SYMC_NBAPP_update-2.6.0.1-1.x86_64.rpm, 81 bytes, 1 tape blocks
khepx007:/var/opt/ignite/recovery/mec#

 

notice the file size of the 3rd file its supposed to be alot bigger..not sure of the exact size, symantec havent told me

but the total size is over 9G

i even set ulimit to unlimited just to verify that it wasnt that also.

Re: Size restriction on tar command

These appear to be Linux files, why are you using HP-UX's tar?  Perhaps you need gnu tar?

Re: Size restriction on tar command

It actually ended up being a weird setup from symantec, we had to do it different and on the PC side this time...

thanks everyone
