Yes. You can use multipath on Netezza linux hosts (Redhat 5/6 based) - ust when you set it up be aware about configuring it properly:

Hi
Under the hoods Netezza (PureData for Analuytics) is just RedHat. For SAN connections you can simply:
1. Connect Netezza hosts (remember to do on both of them) to brocade/SAN switch
2. Present LUNs to Netezza hosts
3. Scan LUNs
4. Create PV->VG->LV-> format FS
All as described here:
https://www.ibm.com/support/pages/adding-san-storage-puredata-system-analytics
Few things:
Netezza doesn't support multi-journal file systems: do not install GFS/GFS2. If you want multi-mount you need to use GPFS (ask IBM sells rep for license)
ie. You can only use created filesystem on single host at once. Good news is that you can add SAN storage to cluster (but remember to make sure both hosts see same VG/Filesystem prior to adding it)
And to answer your question short: yes - multipath is supported. Just when you create PVs, use dm devices instead sdX (ans same constaint as above: make sure 2nd host see the same)
