| shashi_sa | Hi All , i have few ubuntu boxes , sometimes disk failes in our servers, at that time , if we look at log files , we observe scsi id's , like sd08:12 . My questions , where i can find a map file which conatins mapping of scsi ids corresponds to which partition/disk ? | 03:09 |
| === tuxmaniac [n=aanjhan@unaffiliated/tuxmaniac] has joined #ubuntu-kernel | ||
| BenC | shashi_sa: Generally you go by info in /proc/scsi/ | 03:38 |
| BenC | shashi_sa: There should be a mapping for the bus/target/lun in there | 03:38 |
| shashi_sa | K | 03:38 |
| mjg59 | 08:12 looks like major/minor | 03:39 |
| BenC | If you have more than one bus, then it can be a little ambiguous, but hopefully your scsi bus's don't contain the exact same devices in that case :) | 03:39 |
| mjg59 | shashi_sa: If you ls -l /dev/sda1, it'll be 08:01 | 03:39 |
| mjg59 | Other partitions should have similar numbering | 03:39 |
| kylem | it's complicated... | 03:41 |
| === sky_walkie [i=czzhrd02@xdsl-563.lodz.dialog.net.pl] has joined #ubuntu-kernel | ||
| shashi_sa | I know about this , but scsi files mention only bus/target/lun information , but the message i am getting are like sd08:17 sd08:12 | 03:47 |
| mjg59 | shashi_sa: Check the major and minor numbers on the device nodes | 03:48 |
| shashi_sa | K | 03:48 |
| BenC | shashi_sa: Also, dmesg on boot should show the bus/target/lun during the probe, and show the /dev/sdXX to go with it, which should help you map them | 03:48 |
| shashi_sa | brw-rw---- 1 root disk 8, 1 Mar 19 2002 /dev/sda1 | 03:50 |
| mjg59 | shashi_sa: So sda1 is 08:01 | 03:51 |
| mjg59 | shashi_sa: Now you get to check which is 08:12 | 03:51 |
| kylem | 08:12 is always going to be sda12... | 03:52 |
| mjg59 | kylem: Where does sdb start? | 03:52 |
| kylem | 08:16 | 03:52 |
| kylem | it's maj:16*n | 03:53 |
| mjg59 | Ah, right. I couldn't remember how many partitions we supported on scsi | 03:53 |
| kylem | there's a lot of scsi majors, but the first 16 disks are all on 8. | 03:53 |
| === Lure_ [n=lure@external-7.hermes.si] has joined #ubuntu-kernel | ||
| shashi_sa | No , if i am getting errors like sd08:17 sd08:12 , but i don't partitions only upto 6 . sdb6 is my last partition | 03:57 |
| shashi_sa | I don't have 12 or 16 partitions in my disk , i have only 6 partitions on each and evry disk | 03:58 |
| shashi_sa | K , are you guys saying "if it is sd08:<16 , then it is first hard disk , and if it is sd08:>=16 , then it is second disk" ? | 04:03 |

| kylem | /proc/scsi/scsi should tell you what you need. are these sata or pata disks? | 04:05 |
| shashi_sa | Attached devices: | 04:06 |
| shashi_sa | Host: scsi0 Channel: 00 Id: 00 Lun: 00 | 04:06 |
| shashi_sa | Vendor: SEAGATE Model: ST336607LC Rev: 6D01 | 04:06 |
| shashi_sa | Type: Direct-Access ANSI SCSI revision: 03 | 04:06 |
| shashi_sa | scsi disks | 04:06 |
| shashi_sa | But looks like /proc/partitions file contains all information what i am looking for | 04:12 |
| kylem | ah. ok. | 04:12 |
| shashi_sa | But still i am not understanding , i got 35k errors on sd08:12 , but i don't have 12 partitions on my disk , even /proc/partitions file don't contains 8 12 word , so still i am not understanding sd08:12 refres to which disk/partition ? | 04:15 |
