SLOW mksysb
Hello.

I am running AIX 5.2 on a 9131-52A

I am trying to run a mksysb. I ran one on a similar 9131 and it did not take long at all. But this one is taking forever. My output is as follows:

*********************************************************
AIX:/ # mksysb -i /dev/rmt0

Creating information file (/image.data) for rootvg.

Creating tape boot image ..
bosboot: Boot image is 18795 512 byte blocks.


Creating list of files to back up
Backing up 55618 files..............................
17317 of 55618 files backed up (31%)..............................
17319 of 55618 files backed up (31%)..............................

*********************************************************

And this is still running at only 31%. It has been going for at least an hour.
My block size on my drive is 0. It is an internal 4mm DAT72 drive. I am not getting dinged with any entries in the error report.

Any suggestions would be helpful before I call Big Blue.

Thanks
Mike

vgcfgbackup

VGCFGBACKUP(8)						      System Manager's Manual						    VGCFGBACKUP(8)

NAME

       vgcfgbackup - backup volume group descriptor area

SYNOPSIS

       vgcfgbackup [-d|--debug] [-h|--help] [-v|--verbose] [VolumeGroupName...]

DESCRIPTION

       vgcfgbackup  allows you to backup the metadata or Volume Group Descriptor Area (VGDA) of one to all volume groups to files in /etc/lvmconf.
       If you don't give any volume groups in the command line, all of them will be backed up.	This DOESN'T backup user/system  data  in  logical
       volume(s)!   To	restore  volume  group	descriptor area backups see the vgcfgrestore(8) tool.  A 10 step history is backed up in /etc/lvm-
       conf/VolumeGroupName.conf and  /etc/lvmconf/VolumeGroupName.conf.[1-9].old. This enables you to restore your volume group configuration	up
       to 10 steps back in the backup history.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about vgcfgbackup's activities.

DIAGNOSTICS

       vgcfgbackup returns an exit code of 0 for success and > 0 for error:

       1  error doing backup

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line
