Solaris FC SAN multi-path problem
by Steve Losen 19 Aug '05

19 Aug '05

Another Solaris and Netapp FC SAN puzzler... We have two Solaris 8 hosts connected to a FAS960c pair via two FC SAN switches. These hosts do not have Veritas VxVM installed. Instead we are doing multipathing with the Solaris scsi_vhci driver. The filers are running 7.0.1R1 with "cfmode partner". They occasionally whine because the Suns are using the secondary paths to some of the LUNs, i.e., through the partner filer's 7b or 9b ports. I ran this command on the Sun boxes, which shows the available paths to a LUN: luxadm display -p port-wwn-of-filer For example, luxadm display -p 500a098186c7ad4d This shows 4 paths to the LUN, which is correct, but they are all "primary": DEVICE PROPERTIES for disk: 500a098186c7ad4d Status(Port A): O.K. Status(Port B): O.K. Vendor: NETAPP Product ID: LUN WWN(Node): 500a098086c7ad4d WWN(Port A): 500a098386c7ad4d WWN(Port B): 500a098c86c7ad4d Revision: 0.2 Serial Num: C4a9a3zV1-yc Unformatted capacity: 102400.000 MBytes Read Cache: Enabled Minimum prefetch: 0x0 Maximum prefetch: 0x0 Device Type: Disk device Path(s): /dev/rdsk/c4t60A980004334613961337A56312D7963d0s2 /devices/scsi_vhci/ssd@g60a980004334613961337a56312d7963:c,raw Controller /devices/pci@1e,600000/SUNW,qlc@2/fp@0,0 Device Address 500a098386c7ad4d,0 Host controller port WWN 210000e08b1ee380 Class primary State ONLINE Controller /devices/pci@1e,600000/SUNW,qlc@2/fp@0,0 Device Address 500a098c86c7ad4d,0 Host controller port WWN 210000e08b1ee380 Class primary State ONLINE Controller /devices/pci@1e,600000/SUNW,qlc@2,1/fp@0,0 Device Address 500a098186c7ad4d,0 Host controller port WWN 210100e08b3ee380 Class primary State ONLINE Controller /devices/pci@1e,600000/SUNW,qlc@2,1/fp@0,0 Device Address 500a098a86c7ad4d,0 Host controller port WWN 210100e08b3ee380 Class primary State ONLINE In the above output, the paths involving 500a098a86c7ad4d 500a098c86c7ad4d ^^ ^^ correspond to the partner filer's 9b and 7b ports and yet they have Class primary, so it is no wonder that the Suns use these paths sometimes. Here are the four paths in a more comprehensible form: host port A --> FC switch 1 --> local filer port 7a host port A --> FC switch 1 --> partner filer port 7b host port B --> FC switch 2 --> local filer port 9a host port B --> FC switch 2 --> partner filer port 9b I have checked the igroups and LUN mappings and cfmode and cabling, etc., and all are correct. The paths are all there and they are all correct. The only problem that I see is that they are all "primary". For what it is worth, we have some Suns on the SAN that are using Veritas multipathing and Veritas can tell the difference between a primary and secondary path. Does anyone have any suggestions for fixing this? This problem isn't a show stopper, just more of an annoyance because occasionally the filer sends autosupport to netapp about it.

New Idea for Netapp..Filer as a syslog master host
by Greg Wilson 19 Aug '05

19 Aug '05

Netapp Filer as a syslog master host. I want to set our 200+ unix servers to send all their syslog messages/data to the netapp and then archive all the data to a Snaplock Volume. Other things that would make it better - The netapp could do make a snap lock volume every week and keep it for x number of years. - The netapp can have a seperate qtree for each host sysloging to it. - Different data retention periods for different classes of hosts -- Greg Wilson Senior System Administrator greg.wilson(a)aapt.com.au

OnTap & LDAP authentication method
by Jeff Bryer 17 Aug '05

17 Aug '05

I'm trying to configure up our new NetApp (FAS3020) running OnTap 7.0.1R1 to use LDAP for authentication. When it binds to our server it is using method=163 which is SASL. How can I change it to use simple authentication (the equivalent of the -x flag on ldapsearch)?

Trap Mapping Tests
by Robert Borowicz 17 Aug '05

17 Aug '05

Is there a way to trigger a trap to be sent by a Filer (DOT 6.5.4) to a Net Mgmt station for testing? I have Aprisma's (old Cabletron now owned by CA) Spectrum in house and have my filer modeled in the Spectrum database as a Generic SNMP model. Spectrum allows you to add OID's to the existing Gen SNMP model extending Trap support. Mapping Traps into Spectrum for the filer has numerous benefits for me not the least of which is I can then create an Alarm in Spectrum and use my dedicated Paging Server machine (which dials my Paging provider directly and does not rely on the Network to send an email-page) to notify me of Filer Events such as failed disk or P/S. I have downloaded the MIB from the NOW site for 6.5.4 to reference the OID's I'll need to feed to Spectrum. Now I want to trigger an actual Trap for a given Filer event to test my mapping and what the Filer *actually* sends out. Anybody do this already? Thanks -Bob Borowicz

netapp + solaris + veritas dynamic multipathing problem
by Steve Losen 15 Aug '05

15 Aug '05

We have 3 email servers running Solaris 8 and Veritas 4.1 and a fas960c pair running DOT 7.0.1R1. These are all connected to a pair of FC SAN switches. Each email server has 4 LUNs, 2 from each filer, for a total of 12 LUNs. Dynamic multi-pathing works fine on two email servers. However, on one server, DMP works for two LUNs and fails for two. The two LUNs that fail are coming from the same filer. If we "cf takeover" on one filer, the two LUNs get I/O errors. It doesn't matter which filer runs "cf takeover". We have been trying to isolate the problem. The email servers are essentially identical, with the same patches and the same Veritas package installed. lun show -v on the filers does not show any difference that matters. All LUNs are "Multiprotocol Type: solaris". We ran the veritas command to show all the paths to the LUNs and we do not see any obvious problem with the LUNs that fail. We have the right number of paths and they are correct. The paths that are supposed to be primary are indeed primary, ditto for secondary. We have ports 7a and 7b from both filers connected to one switch and 9a and 9b connected to the other. The email hosts all have dual port Qlogic HBAs and we have the ports plugged into different switches. The switches are not directly connected to each other. A little more background -- A week ago we were running an older version of veritas, had only one SAN switch (instead of two) and had only one FC target adapter in each filer, and we had this same problem. So even after this major SAN reconfiguration and software upgrade, the same problem persists. Does anyone have any ideas? We are thinking about creating two new LUNs, migrating the data over from the bad LUNs and deleting them. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support
