Hi, I realize this might not be strictly GPFS related but I’m getting a little desperate here… I’m doing an implementation of GPFS/Spectrum Scale 4.2 at a customer and struggle on a question of disk multipathing for the intended NSD disks with their direct attached SAS disk systems. If I do a multipath –ll, after a few seconds I just get the prompt back. I expected to see the usual big amount of path info, but nothing there.
If I do a multipathd –k and then a show config, I see all the Dell disk luns with reasonably right parameters. I can see them as /dev/sdf, /dev/sdg, etc. devices. I can also add them in PowerKVM:s Kimchi web interface and even deploy a GPFS installation on it. The big question is, though, how do I get multipathing to work ? Do I need any special driver or setting in the multipath.conf file ? I found some of that but more generic e.g. for RedHat 6, but now we are in PowerKVM country. The platform consists of: 4x IBM S812L servers SAS controller PowerKVM 3.1 Red Hat 7.1 2x Dell MD3460 SAS disk systems No switches Jan ///Jan [cid:E11C3C62-0896-4FE2-9DCF-FFA5CF812B75] Jan Finnerman Senior Technical consultant [CertTiv_sm] [cid:621A25E3-E641-4D21-B2C3-0C93AB8B73B6] Kista Science Tower 164 51 Kista Mobil: +46 (0)70 631 66 26 Kontor: +46 (0)8 633 66 00/26 [email protected]<mailto:[email protected]>
