Re: AIX 5.3 Snapdrive 4.2 not working

peterkain42 · ‎2011-10-05

We recently purchased and setup a FAS3240 running 8.0.1P5 and I'm having trouble with Snapdrive on our AIX host.

After installing Snapdrive 4.2 I can run some commands, but can't create a snapshot.

The LUNs mounted on the host via FC were created on the filer not w/ Snapdrive but the snapdrive command doesn't associate them with the hosts.

We can lists the LUNs (see below). Notice we see the LUNs with the "sanlun" command.

We made just a couple changes to the snapdrive.conf file:

autosupport-enabled=on # Enable autosupport flag

default-transport="FCP" # Transport type to use for storage provisioning, when a decision is needed

multipathing-type="NativeMPIO" # Multipathing software to use when more than one multipathing solution is available. Possible values are 'DMP', 'NativeMPIO' or 'none'

We use AIX LVM and JFS2 which are defaults.

Details:

FAS3240A> options trusted.hosts

trusted.hosts * (same value required in local+partner)

AIX 5.3 TL 12

- Snapdrive 4.2 for AIX installed

bash-2.05b# lslpp -l | grep -i snap

Are WWPW of local adapters correctly found? What is result of

sanlun fcp show adapter -v

sanlun fcp show adapter -c

And on filer

igroup show -v <the name of your AIX igroup

Our VAR and then we checked that our hardware/software is supported in the Support Matrix. But when I run the sdconfcheck the last line doesn't look right (i'm going to post this as separate question just so more people may see it).

For some reasons it finds old version of host utilities. It could be the cause of your problem.
