Our NIM server has a filesystem named /export/mksysb just to hold mksysb images. We use to have the client LPARs NFS mount this filesystem and create their backups there, but with AIX 6.1 TL5, the NIM server doesn't like it when there is already a /export/mksysb entry in the /etc/exports that he didn't put there. Now, we have our NIM server tell the clients to create their mksysb's to the same /export/mksysb filesystem on our NIM server. The difference is that the backups are being handled by our NIM server and it maintains the entries in the /etc/exports file. These are the NIM commands that we use:
First remove the old mksysb resource and file to create enough space for a new mksysb:
Create a new mksysb file and NIM resource:
Also, the NIM server doesn't like to make 2 mksysbs going on at the same time because it may not complete correctly due to limited amount of space in the /exports/mksysb filesystem. This can be over riden by adding the "-F" option to the first part like this:

Hi All
i have a number of IBM servers with different models, and i want to do a backup for the rootvg using mksysb and that backup will be stored on a 4mm DDS tape.
i have only one machine (p550) which i can use it for testing purposes, so the quesion is that can i test my mksysb backups on... (6 Replies)
hi guys,

Hello,
Last night I applied a DB2 fix pack which is now causing problems with the application that uses db2. Prior to applying the fix pack I did a mksysb(rootvg) which includes the file system that has db2 installed on it. If I do a restore from this will it restore the db2 version back to... (1 Reply)

mountd
mountd(8) System Manager's Manual mountd(8)NAME
mountd - Services remote NFS compatible mount requests
SYNOPSIS
mountd [-d] [-i] [-n] [-s] [exportsfile]
FLAGS
Verifies the Internet addresses of hosts that make mount and unmount requests. If a client's address cannot be translated into a host name
by the gethostbyaddr() function and then translated back into the same Internet address by the gethostbyname() function, the request is
rejected.
This option requires the BIND service for Internet address resolution. It offers the highest level of security, especially when
combined with the -i option. Turns on Internet address verification and domain checking. If you are running the BIND service,
mountd verifies that a host making a mount or unmount request is in the server's domain. Allows non-root mount requests to be
served. This should only be specified if there are clients such as PC's that require it. ULTRIX BSD is allowed non-root mount
requests by default. Use the -n flag to allow non-root mount requests. Verifies the Internet address of hosts that make mount and
unmount requests. If a client's address cannot be translated into a host name by the gethostbyaddr() function, the request is
rejected. If you are running the BIND service, the BIND server is used to translate the address. If you are not, the /etc/hosts
file is used.
If the -i option is not used and a client's address cannot be translated, the address is converted to a string of the form
xx.xx.xx.xx. This allows access to exported file systems that do not specify a list of allowed hostnames.
The -i option is automatically enabled when either the -d or the -s option is specified. Turns on Internet address verification and
subdomain checking. If you are running the BIND service, mountd verifies that a host making a mount or unmount request is in the
server's domain or subdomain.
DESCRIPTION
The mountd daemon is the server for NFS protocol mount requests from clients. The mountd daemon responds to requests from remote computer
systems to mount directories. When it receives a SIGHUP signal, mountd rereads the exports file. If you are on an NFS client and want to
have changes to the export options on existing NFS client mounts take effect immediately, issue the showmount -e command and specify the
name of the host that is exporting the directory or file system (where the exports file is located). This ensures that NFS is aware of the
export list and options.
The optional exportsfile argument specifies an alternate location for the exports file. /etc/exports is the default.
Note, NFS Version 2 can export partitions that are greater than 2 gigabytes. However, they appear as 2 gigabyte partitions when viewed
from NFS clients.
