Hi, I need to upgrade SDDPCM from devices.sddpcm.53.rte.2.2.0.4 to devices.sddpcm.53.rte.2.6.0.3 (this will also include an upgrade to devices.fcp.disk.ibm.mpio.rte). Is it as simple as a smitty update_all and then a reboot as I am staying at devices.sddpcm.53.rte ? Aswell as on AIX lpar, I...

Can i create an additional filesystem on a VIOS ? I want to run nmon and want a location to store the output files ? Would it be better practice to just create an nmon directory under /home/padmin ? Can anyone tell me what the IBM directive or recommendation on this is. Thanks.

Could someone please explain something too me. I am trying to work out what processes are using paging space and how much. myserver# lsps -a Page Space Physical Volume Volume Group Size %Used Active Auto Type hd6 hdisk0 rootvg 4096MB 4 yes yes...

I have just taken over 2 VIOS installations on different servers - 1 ioslevel is 1.5.2.1-FP-11.1 2 ioslevel is 1.5.2.5-FP-11.1 SP-01 My understanding is that these are both at version 1.5 and FP 11.1 and one has SP01 - what does the 2.1 and the 2.5 represent in the ioslevel command output...

i would say fred had never logged on when you ran lsuser with ALL and then logged on before you ran lsuser with just fred. what happens if you run - lsuser -a id gecos account_locked time_last_login fred then lsuser -a id gecos account_locked time_last_login ALL | grep fred

I have re-read the manual and - secondly, we are using ipat via ip alias and also hb over ip aliasing. the boot and service address are on the same network but the ip address offset is on a different subnet. i thought boot and service had to be on different subnets ? is this the case even...

Hi, I have 2 questions. I have taken over a cluster that is soon to go into production and i have started some testing. i have 1 IP and 1 non-IP network. The IP network is an etherchannel, i ifconfig enX down and the cluster detects the network down, but without any manual intervention after...

mkdir -m

i think i have done something like this before. i think you can edit /image.data on your source system, there are various COPIES=2 that need changing to COPIES=1 under the lvdata stanza. Create another mksysb on your source system but don't create a new image.data (don't include the -i...

can someone please confirm or comment on my understanding of cpu/core/vcpu/lcpu is correct - profile - uncapped partiton proc unit 0.1/0.4/8 vcpu 1/4/8 so each vcpu will have a guaranteed 10% of a processing unit (a core ? - 16 cores on an 8 cpu dual core server ?) as the partition is...

have a look at - http://www.ibm.com/developerworks/aix/library/au-aixpartition/ http://www.ibm.com/developerworks/wikis/display/WikiPtype/Home (good portal) hope this helps !

Have a look in the HACMP Installation Guide - http://publib.boulder.ibm.com/epubs/pdf/c2352091.pdf I am sure it documents how to test this.

I think the 'IBM recommended' way would be to change the rss attribute with chuser - xxxx1234(root)# lsuser -a rss user1 user1 rss=65536 xxxx1234(root)# su - user1 xxxx1234(user1)# ulimit -m 32768 xxxx1234(root)# chuser rss=131072 user1 xxxx1234(root)# su - user1 xxxx1234(user1)# ulimit -m...

hi, i am looking at authenticating linux/unix users against active directory but i want to restrict access to certain hosts for certain users. there is a config change on the ldap client for pam to check the host value but i cannot see where or how add associate/add a list of hosts to a user...

CWS is the Control Workstation in an SP environment. while the SP nodes do not need the CWS once they are up and running, they do need it for install as it is not only the NIM master, but also contains the SDR which is the repository for the node configuration. i cannot remember exactly, but i...

have a look at the performance section on http://aix.lap.hu/ one comment - it is very important to have a good understanding of what you are doing as incorrect configution changes could compound performance problems !

schedule nmon via cron to capture performance date between the times you interested in. this will create a file you can view in excel.

does mkuser work on the command line ?

you need to add the server back as nim client on your nim master. smitty nim_mkmac should fastpath you to the 'define a machine' panel. it is also worth a look at http://www.redbooks.ibm.com/redbooks/pdfs/sg247296.pdf for all the NIM info you will ever need !!
