Hi everyone,
I want to clone a AIX 5.2 system from a machine to another one.
So i modified bosinst.data and image.data files (according to future platform) before making mksysb on old platform.
After booting on CD and restoring system using mksysb tape, the installation is launched but ever... (2 Replies)
Hello,
With AIX 5.3 is it possible to run a mksysb with users logged into the system?
The users are accessing a database app that runs on a separate physical disk than the system files. Does this even matter?
Thanks (1 Reply)
I use AIX 5.2 I want to allow a non-root user to do a system backup with 'mksysb' command.
I try to add 'ManageBackup' Role to that non-root user but it have an error "ksh: mksysb: 0403-006 Execute permission denied."

I have several Solaris 8,9 and 10 servers.
I need to refresh them and avoid doing any OS upgrades. I may have to apply patches when I am done due to the new hardware.
My current servers have internal disk and my new target servers (same processor types) will have only SAN storage. Once the... (0 Replies)
Hi,
In order to have a sand box machine that I could use to test some system changes before going to production state, I'd like to duplicate a working system to a virtual one. Ideally, I'd like to manage to do it this way :
- Make a full system backup excluding the user file system (this... (7 Replies)

Hello there,
I would like to protect a Linux system from cloning, I don't mind if the cloned hard drive works in the same computer, but I need to avoid it to work in other one, even if it uses exactly same mainboard model and rest of computer parts. I want the cloned system to get frozen or... (4 Replies)

mt
MT(1) BSD General Commands Manual MT(1)NAME
mt -- magnetic tape manipulation
SYNOPSIS
mt [-f tapename] command [count]
DESCRIPTION
The mt program is used to give commands to a magnetic tape drive. By default mt performs the requested operation once. Operations may be
performed multiple times by specifying count.
Note that tapename must reference a raw (not block) tape device. If tapename is of the form "host:tapename", or "user@host:tapename", mt
writes to the named tape device on the remote host using rmt(8).
The rmt(8) process on the remote host is typically initiated via rsh(1), although an alternate method such as ssh(1) can be specified via the
RCMD_CMD environment variable.
The available commands are listed below. Only as many characters as are required to uniquely identify a command need be specified.
asf Move forward count files from the beginning of the tape. This is accomplished by a rewind followed by fsf count.
eof, weof Write count end-of-file marks at the current position on the tape.
fsf Forward space count files.
fsr Forward space count records.
bsf Back space count files.
bsr Back space count records.
rewind Rewind the tape. (The count is ignored.)
offline, rewoffl
Rewind the tape and place the tape unit off-line. Where supported, this ejects the tape. (The count is ignored.)
status Print status information about the tape unit. (The count is ignored.)
retension Retensions the tape. Not all tape drives support this feature. (The count is ignored.)
erase Erases the tape Not all tape drives support this feature. (The count is ignored.)
eew Enable or disable early warning EOM behaviour. Set count to nonzero to enable, zero to disable.
eom Forward space to the end of recorded media. (The count is ignored.)
blocksize, setblk
Set the tape blocksize to count bytes. A count of zero sets variable blocksize.
density, setdensity
Set the tape density code to count as specified in the SCSI-3 specification. See the DENSITY CODES section for a list of codes
for commonly used media types.
rdspos Read the logical block position of the tape. Not all tape drives support this feature. (The count is ignored.)
rdhpos Read the hardware block position of the tape. Not all tape drives support this feature. (The count is ignored.)
setspos Set the logical block position of the tape to count. Not all tape drives support this feature.
sethpos Set the hardware block position of the tape to count. Not all tape drives support this feature.
compress If count is zero, disable compression. Otherwise enable compression. Not all tape drives support this feature.
If a tape name is not specified, and the environment variable TAPE is not set, then mt uses the device /dev/nrst0.
ENVIRONMENT
If the following environment variables exist, they are used by mt.
TAPE mt uses device filename given in the TAPE environment variable if the tapename argument is not given.
RCMD_CMD mt will use RCMD_CMD rather than /usr/bin/rsh to invoke rmt(8) on a remote machine. The full path name must be specified.
FILES
/dev/rst* Raw SCSI tape device
/dev/rmt* Raw magnetic tape device
EXIT STATUS
mt returns a 0 exit status when the operation(s) were successful, 1 if the command was unrecognized, and 2 if an operation failed.
DENSITY CODES
The SCSI-3 specification defines a number of density codes for various tape media, some of which are listed here. Note that many tape drive
vendors also define model-specific codes.
