Hello,
I have some concerns over the disk management of my AIX system.
For example server1
Code:
[root@server1] / > lspv
hdisk0 00fa6d1288c820aa rootvg active
hdisk1 00fa6d1288c8213c vg_2 active
hdisk2 00c1cc14d6de272b vg_3 active
hdisk3 00c1cc14d6de27e5 vg_3 active
hdisk4 00c1cc14d6de2898 vg_3 active
hdisk5 00c1cc14d6de2958 vg_3 active
hdisk6 00c1cc14d6de2a07 vg_3 active
hdisk7 00c1cc14716beb5c vg_3 active
hdisk8 00c1cc14816d37d0 vg_2 active
hdisk9 00c1cc14816d38a0 vg_3 active
hdisk10 00c1cc14816d396c vg_3 active
hdisk11 00c1cc14716beb98 vg_3 active
hdisk12 00c1cc14716bebd9 vg_3 active
hdisk13 none None
[root@server1] / > mpio_get_config -A

hdisk1 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk2 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk3 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk4 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk5 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk6 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk7 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk8 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk9 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk10 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk11 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk12 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk13 Available 23-T1-01 MPIO FC 2145
So my questions are:
1. I can see there is 14 hdisks (from hdisk#0 to hdisk#13, come from DS5K) but in the mpio_get_config I only see 13 hdisks (from hdisk#0 to hdisk#12), the hdisk#13 is the new one from different storage V7000.
From my point of view, the mpio_get_config command should display the mpio info of hdisk#13 as well?
2. What difference between this? It should be show the same drivers as the driver is AIX PCM?
Code:
hdisk12 Available 23-T1-01 MPIO DS5100/5300 Disk
hdisk13 Available 23-T1-01 MPIO FC 2145
3. And in the server2, the mpio_get_config command even returns no results
Code:
[root@server2] / > mpio_get_config -A
Error: Unable to find devices.
Can we know in which context mpio_get_config command is applicable?
We are looking at running MPIO for it's redundancy and load balancing benefits. Does anyone know what pieces of software or modules are needed on the VIO server to get load balancing to work. Remember we are using EMC's DMX3500 storage system. We no longer want to use Powerpath. :rolleyes: ... (2 Replies)
Hi
I would like to ask what the benefits are of changing from RDAC to MPIO when connecting to a DS4000 on AIX 5.3? I have heard that IBM MPIO "might" support more than 1 active path to a LUN when connecting to a DS4800 through more than 1 host connection on the same AIX client. I understand that... (8 Replies)
Hi folks,
does anybody have a link to a documentation how to implement native MPIO on AIX? We are using EMC PowerPath and Datacore SanSymphony/Cambex for this so far and I wasn't able to find a good description on that topic. All I know so far is that mkpath, chpath and lspath are used to... (3 Replies)
Can anyone recommend me some reading material surrounding how AIX handles LUNs:
- with and without MPIO installed
- with and without SDD or SDDPCM installed
Where does lspath sit in all of this (MPIO layer?). Can a system be built with just MPIO software? Is MPIO software even needed?
I guess... (0 Replies)
On a particular LPAR, I was running AIX 5.3 TL 3. On Monday I did an update of the LPAR to 5.3 TL 9 SP2. The install was smooth, but then I ran into a problem.
The MPIO driver does not work with LSI's StoreAge (SVM4). I did some looking, and looks like
5.3 TL3 = IBM.MPIO 5.3.0.30

Hi,
we have a vew boxes using MPIO and they are connected to some virtualization software managing some disk subsystems, offering volumes to the AIX boxes.
Sometimes when a cable has been plugged out for a test or when a real problem occurs, using lspath to show the state of the paths shows... (8 Replies)
Hello,
we are planning to deploy some of our databases on AIX/LPAR based servers (we didn't bought it yet ...). IBM's engineers says that if we want to boot them from SAN the hardware array has to be compatible with MPIO but they don't want to deliver any document with list of arrays supported... (5 Replies)
We have AIX 6.1 system attached to SAN disks (DS4700 and DS8100) thru SVC.
Initially when the system was I forgot to install sddpcm drivers. and wanted to know how can i go with the installation of the sddpcm drivers.
