Hi, I am trying to configure PAV on RHEL 4 and am running into a problem. I have been working from the "How to Improve Performance with PAV November 17, 2006" document.
So it appears PAV is configured. i.e. DASD 0100 ON DASD 304F R/W 0X0100 SUBCHANNEL = 0000 *DASD 0101 ON DASD 314F R/W 0X0101 SUBCHANNEL = 0001* DASD 0190 3390 520RES R/O 107 CYL ON DASD 300B SUBCHANNEL = 0008 DASD 0191 3390 VM350B R/O 470 CYL ON DASD 350B SUBCHANNEL = 000C DASD 019D 3390 V01W01 R/O 146 CYL ON DASD 330B SUBCHANNEL = 0009 DASD 019E 3390 V01W01 R/O 250 CYL ON DASD 330B SUBCHANNEL = 000A DASD 0200 9336 (VDSK) R/W 524288 BLK ON DASD VDSK SUBCHANNEL = 0016 *DASD 0201 ON DASD 31B0 R/W 0X0101 SUBCHANNEL = 0002* DASD 0592 3390 V01W01 R/O 67 CYL ON DASD 330B SUBCHANNEL = 000B # vmcp q pav 314f Device 314F is a base Parallel Access Volume with the following aliases: 31B0 However, after loading the kernel module: dm_multipath 43792 0 and starting multipathd, oh and modifying the /etc/multipath.conf to comment out the blacklist (and yes I modified the file before starting multipathd) I still get no results when I run mulipath. # multipath # When I run multipath -v3 -d I get the following: load path identifiers cache ux_socket_connect error # # all paths in cache : # path dasda not found in pathvec ===== path info dasda (mask 0x1f) ===== path dasdb not found in pathvec ===== path info dasdb (mask 0x1f) ===== path dasdc not found in pathvec ===== path info dasdc (mask 0x1f) ===== path dasdd not found in pathvec ===== path info dasdd (mask 0x1f) ===== md0 blacklisted ram0 blacklisted ram10 blacklisted ram11 blacklisted ram12 blacklisted ram13 blacklisted ram14 blacklisted ram15 blacklisted ram1 blacklisted ram2 blacklisted ram3 blacklisted ram4 blacklisted ram5 blacklisted ram6 blacklisted ram7 blacklisted ram8 blacklisted ram9 blacklisted I am concerned about the ux_socket_connect error and the not found in pathvec errors. Anyone know what might be going on here? Am I missing something here? thanks!
