Fedora 11. Im trying to setup kickstart so it lays out a mirrored volume group. I have 2 disks sda and sdb. I want a primary partition on each disk 200mb in size for /boot. This is to be mirrored onto raid device md0 (raid 1). The rest of each disk is to be setup partition which grows to use...

they are indeed hot swappable. lsslot -c pci This shows you the hit swap pci slots on your system.

Are you sure the adapter is assigned correctly to your lpar ?

Presumably you have 2 fibre adapters in your active cluster node. If so, you could hot swap the failed adapter without taking down the service, or failing the service over.

You might want to consider looking at multibos too, as an alternative to alt_disk_install. Multibos is now my preferred method for upgrading AIX, although it does require you have sufficient space in your rootvg...

I would strongly recommend you download and read the AIX LVM redbook. AIX Logical Volume Manager from A to Z: Introduction and Concepts http://www.redbooks.ibm.com/redbooks/pdfs/sg245432.pdf and AIX Logical Volume Manager from A to Z: Troubleshooting and Commands...

bootinfo -s hdisk18 This tells you the size in MB of the device

Yes, did try, but wasnt that. Got around the problem by waiting for the network to time out. Evetually a login prompt appeared on the console.

Anyone know what the default single user mode password is for VIO ? The version I am using is 1.5 FP 10. Its hanging on boot due to network type issues, meaning i never get a login prompt. Booted to single user mode so i could have a look around, but it asks for a password, and I dont know...

Rename or remove topas binary, and use nmon instead. :-) yes, i know they are now the same, but im assuming your not at AIX 6.1 TL2 or 5.3 TL9 yet. :0)

Its Oracle datafiles with CIO, so these files arent cached.

yes, you can use alt_disk_install to migrate. Clone to a spare disk (or split your rootvg mirror if you need to). You can either boot from clone, or upgrade the running instance. As a precaution, i would boot to the clone, and then upgrade that.

Hi Crypto Yes, i have already used fileplace, and have confirmed heavily fragmented files. I was really looking to see if there was a way to resolve this, but without having to go through the pain of backing up, deleting and restoring data into new filesystems. I just dont understand why...

Hi Khalid It just seems like a drastic thing to have to do.

no, defragfs does not defrag fragmented files. from the LVM redbook. Running defragfs does not solve the problem of fragmented files. The Defragfs command only reorganizes the free disk blocks so more contiguous free space is available.

Hi All What is the best way to deal with heavily fragmented files on a jfs2 filesystem ? I have seen other threads where it has been suggested that removing data from the filesystems, either by copying to temp location, create new filesystems, and then restore. I was rather hoping that would...

Ive found some notes online which indicate that extension of stiped logical volumes can be achieved by adding additional striped columns. http://www.ibm.com/developerworks/aix/library/au-aix5l-lvm.html However, what Im really after is the ability to increase the existing stripe width online. I...

I saw an earlier thread regarding VIO and 3rd party monitoring agents, but no conclusion as such. Anyone using any 3rd party agents ? In particular Openview.

Cheers P5 !

Been a while since ive done this, so im a little rusty. Heres the scenario. I have 2 VIO servers running on a p570 (primary and standby) providing virtual scsi luns from a DS8000 to my client lpar. VIO1 VTD $ lsmap -vadapter vhost3 SVSA Physloc...
