Hi,
I wanted to attach 600 luns [ emc ] to few linux hosts [ rhel5.2 86_64]. I am testing now with one test server. As per the EMC doc , modfied the /etc/modprobe.conf and added the line options scsi_mod max_luns=1023 max_report_luns=1024 reimage the kernel, and reboot. More than 600 luns are being attached to the server. I am getting all the luns in /proc/scsi/scsi. I am not sure it is a problem or this is the way it should be ... While checking the path with scsi_info ,I am finding that upto 255 the scsi_info is matching with the /proc/scsi/scsi, but when the 256 no. is crossing the scsi_info is getting started with 0 again. For example , I am showing here for the case of one lun. The lsscsi is showing for the luns as follows: [0:0:0:628] disk EMC SYMMETIRX 6777 /dev/sdxe The same is in the /proc/scsi/scsi too, as lsscsi reads the /proc/scsi/scsi only. But when i am trying to check the scsi_info with the path attached to the same lun, the same lun is showing the scsi_id as 0,0,0,116. I checked the bios level, found under configuration , luns per Target = 256, it can't be increased. So my thought is, as this value is 256, so the scsi_id after 255 luns , starting again from 0. In that case , the scsi_info will not be the same with /proc/scsi/scsi. Please advice. Thanks in advance _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
