Small issue in install_dnf.sh

In locales where the decimal seperator is not "." but i.e "," the script fails with: $ ./install_dnf.sh -y ./install_dnf.sh[113]: 2040,74: 0403-057 Syntax error $ Running with "LANG=C ./install_dnf.sh -y" solves the problem. Maybe add a "LANG=C" into the script? ------------------------------ ...

RE: Is anyone testing VIOS 3.1.3.10

No problems so far. Running it on four servers in a test environment with about 50 LPARs over the last month, and in production on eight servers with about 120 LPARS. Only anomaly is that it now set a restricted kernel tunable, but I assume that is intended :) SEA based network with underlying LACP ...

RE: ASM on PowerHA

If you run ASM, it needs access to raw devices. You can provide either PVs or LVs for that purpose. Now, if you ignore licensing, a fully active/active cluster for ASM is the best approach. ASM is always active and controlling disks and you can manage data distribution with whatever tools ASM provides. ...

LVM can also balance through striping, that is basically how ASM does it too. Application controllers and monitors, you just write yourself. ------------------------------ Morten Torstensen TietoEVRY ------------------------------

ASM works fine, but ideally you should run ASM outside of PowerHA control, so ASM is active always on all nodes. This makes failing over database services much faster. This does however require licenses for that. You can also include ASM start/stop on the RG scripts as well, and start/stop everything ...

RE: Support VIOs boot-on-SAN sharing HBA used for NPIV

Found In Egroup: PowerVM \ view thread
It works, it is supported (as, IBM Support will support it) and is the normal way to do it. We have used this setup for 12+ years as we ditched all internal disks and storage options on the POWER servers around that time - and it is a waste of PCI slots or HBA ports to dedicate ports to VIOS disks. ...

Hi, What are the plans to update sudo in the AIX yum repository for this vulnerability? According to the info here and the test, the AIX version is vulnerable: CVE-2021-3156: Heap-Based Buffer Overflow in Sudo (Baron Samedit) | Qualys Security Blog > rpm -qa|grep sudo sudo-1.8.31p1-2.ppc ...

I hope you upgraded the BFF version of openssl and not the RPM...? You way might work, but be careful as you should not mix the YUM repos with Perzl/Bull RPMs as they are not fully ABI compatible and that might come back and bite you later on. RPM and YUM might be happy based on versions and dependencies ...

Looks like you have lots of RPMs installed already? Like openssl? That has to go. What I do is to 1. Save off some config files, like /etc/sudoers and "rpm -qa" output 2. Uninstall all RPMs: rpm -e $(rpm -qa) 3. Install latest rpm.rte 4. updtvpkg, just to be sure all is in sync 5. rpm -Uvh ...

RE: Removal of symlink/files from /usr for AIX Toolbox packages

While I can understand wanting to use bash, it is an ok shell if you "set -o vi", but changing the default shell of the root user is typically not recommended in any unix system. This will affect all system scripts and can lead to strange and unknown bugs. I would not sleep well at night with that. ...

RE: rsync link not included in latest update

Yes, this was a decision a while back. All the packages are removing anything from /usr and put everything in /opt/freeware. This is to avoid the periodical problems of clashes between AIX and RPM files. I would add "/opt/freeware/bin:/opt/freeware/sbin" to your default PATH. Not all RPMs have been ...

Because hdiskXX have different numbers accross the cluster? No need to do anything really, PowerHA makes no assumptions about disk names, so you can just leave it as is and all is fine. However, if you have policies on disk naming or just a streak of OCD - which any good sysadmin have :) - what you ...

Hi! When installing YUM on a newer AIX server (7200-04-02) and using https repos and not http, there are many missing dependencies that are not in the latest yum_bundle_v5.tar file. There is either a very extensive list of required updates to apply before yum can be installed, or I need to temporarily ...
