Oracle Secure Backup - Tape hardware compression: How do i enable/disable it?
Hi,
the 'obtool lsdev -lvg' command shows the following:
=========================================
TAPELTO3:
Device type: tape
Model: none
Serial number: none
In service: yes
Automount: yes
Error rate: 8
Query frequency: 131072KB (134217728 bytes) (from driver)
Debug mode: no
Blocking factor: (default)
Max blocking factor: (default)
UUID: b7044b6c-c84d-102b-9f65-ab6042aa5b56
Attachment 1:
Host: sun440n001
Raw device: /dev/obt0
Connection type: SCSI
Inquiry data:
Vendor: HP
Product: Ultrium 3-SCSI
Firmware: G64D
Serial number: 0836G05338
Tape state: online
Hardware compression: on
Last read was: uncompressed
Maximum block size: 2097152
Remaining tape: 409886720 (uncompressed) blocks (419.72GB)
=========================================
I want to turn off compression. I thought i could use obtar to do this, but obtar requires me to backup.restore data in the process. Does anyone know the command to just enable/disable hardware compression?
