I didn't bother to build it but a little sed/awk/grep-filtering should do the trick nicely.
Any of these would mean that you lost both copies of a certain LP and thus data. In this case you will need to restore the respective LV from backup no matter what. You need to verify of this being the case first, because you will not be able to remove the missing disks with the method i described otherwise.
Hello
I've been working on AIX 5.3 ML3 on IBM pSeries520. That server has 6 HDD drives in 3 volume groups (1+mirror in each group). I must check which phisical disk is which disk in the system. For ex. I want to know that disk in 4th slot in the machine is marked as hdisk5 on AIX. Does anybody... (2 Replies)

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)
We run two p5 nodes running AIX 5L in a cluster mode (HACMP), both the nodes share external disk arrays. Only the primary node can access the shared disks at a given point of time.
We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)

idmap_tdb2 - Samba's idmap_tdb2 Backend for Winbind
DESCRIPTION
The idmap_tdb2 plugin is a substitute for the default idmap_tdb backend used by winbindd for storing SID/uid/gid mapping tables in
clustered environments with Samba and CTDB.
In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new user and group IDs
in order to create new mappings.
IDMAP OPTIONS
range = low - high
Defines the available matching uid and gid range for which the backend is authoritative.
script
This option can be used to configure an external program for performing id mappings instead of using the tdb counter. The mappings are
then stored int tdb2 idmap database. For details see the section on IDMAP SCRIPT below.
IDMAP SCRIPT
The tdb2 idmap backend supports an external program for performing id mappings through the smb.conf option idmap config * : script or its
deprecated legacy form idmap : script.
The mappings obtained by the script are then stored in the idmap tdb2 database instead of mappings created by the incrementing id counters.
It is therefore important that the script covers the complete range of SIDs that can be passed in for SID to Unix ID mapping, since
otherwise SIDs unmapped by the script might get mapped to IDs that had previously been mapped by the script.
The script should accept the following command line options.
SIDTOID S-1-xxxx
IDTOSID UID xxxx
IDTOSID GID xxxx
And it should return one of the following responses as a single line of text.
UID:yyyy
GID:yyyy
SID:yyyy
ERR:yyyy
EXAMPLES
This example shows how tdb2 is used as a the default idmap backend.
[global]
idmap config * : backend = tdb2
idmap config * : range = 1000000-2000000

idmap config * : script = /usr/local/samba/bin/idmap_script.sh
