Centos for aix admin

[tomislak]

Hi,
I'm a aix admin with over 10 years of experience. I need some commands comparison between those two. Espetially commands for disk subsystem. For example how can one see: disk adapter->disk->volume group->filesystem
Thanks.

Been a long time since I did anything with AIX and I have forgotten most of what I knew. I don't think there are direct commands to do what you want but the nearest linux equivalents I can think of are:

Code: Select all

lspci -nn
lshw
fdisk -l 
parted -l
pvs
vgs
lvs

Hi,

thanks for your info.

It seems that I have two fc cards:
root@lin9(/etc)# lspci -nn | grep "Fibre Channel"
06:00.0 Fibre Channel [0c04]: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter [10df:fe00] (rev 02)
06:00.1 Fibre Channel [0c04]: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter [10df:fe00] (rev 02)

and 20 disks
root@lin9(/etc)# pvs

How can I see which disks are from storage and which are local disks?
And how can I see which disk from storage is which disk on lin? Often I have disks from sotrage with same size and this isn't good criteria fro difference.

You could try "lsblk"

Hi,

again me. Is there some course/book/anything for aix to centos/rhel admin migration?

Regards

[aks]

RH used to offer such a course (don't know if they still do), but Google is your friend in this case/ First hit off Google:
https://www.ibm.com/developerworks/aix/ ... -aix_rhel/

[tomislak]

thats in opposite direction, aix for centos admins.
I've google it but with not much valuable info...
