This is a text-only version of the following page on https://raymii.org: --- Title : HP-UX 11.31 System information and find out part number of a failed disk with sasmgr Author : Remy van Elst Date : 18-05-2018 URL : https://raymii.org/s/tutorials/Find_part_number_of_failed_disk_on_HP-UX_with_sasmgr.html Format : Markdown/HTML --- On one of my regular scheduled datacenter visits one of the older HP-UX Itanium machines had an orange light on the front. These systems are not (yet) monitored, but still in use so the disk had to be replaced. Not knowing anything about this system or which parts were used, I managed to find the exact part number and device type so we could order a spare. This small guide uses sasmgr to get the data on HP-UX 11.31.

### Hardware Information on HP-UX Since I normally don't manage these systems and have little experience with HP- UX, I first had to find out some information on the system. Using a few regular Unix tools like `netstat`, `uname` and a few HP-UX specific tools like `model`, `machinfo` I was able to gather basic hardware information of this machine. $ TERM=vt100 ssh hpux09 -l root Last successful login: Fri May 18 08:18:05 METDST 2018 Last authentication failure: Fri May 18 08:10:59 METDST 2018 Last login: Thu Jun 24 09:46:55 2010 from (c)Copyright 1983-2006 Hewlett-Packard Development Company, L.P.

This will go into the hardware documentation, since, sadly, that is very incomplete. ### Disk information Now to the good part, for which we logged in to this machine. Find the serial number and order a new (probably refurbished) disk. The system uses LVM with RAID 1 underneath via a SAS card so when the disk is ordered we can just replace it. If it was just LVM we had to do some configuration This PDF [When _Good_ Disks _Go_ Bad.pdf][2] is very helpfull in preparing and researching this issue. When the new disk is here, [this page][3] will be helpfull for the replacement. The first command shows which disk is the failed one plus the raid configuration: sasmgr get_info -D /dev/sasd0 -q raid Output: Wed May 16 14:54:21 2018 ---------- LOGICAL DRIVE 2 ---------- Raid Level : RAID 1 Volume sas address : 0x3c5c0600358833e Device Special File : /dev/rdsk/c0t3d0 Raid State : DEGRADED Raid Status Flag : ENABLED Raid Size : 139136 Rebuild Rate : 20.00 % Rebuild Progress : 100.00 % Participating Physical Drive(s) : SAS Address Enc Bay Size(MB) Type State 0x500000e01d33a9c2 1 8 140014 PRIMARY ONLINE 0x5000c50003aeb459 1 2 140014 SECONDARY FAILED ---------- LOGICAL DRIVE 7 ---------- Raid Level : RAID 1 Volume sas address : 0xacb8d6daa52eb4d Device Special File : /dev/rdsk/c0t2d0 Raid State : OPTIMAL Raid Status Flag : ENABLED Raid Size : 69878 Rebuild Rate : 0.00 % Rebuild Progress : 100.00 % Participating Physical Drive(s) : SAS Address Enc Bay Size(MB) Type State 0x5000039668124686 1 1 286102 SECONDARY ONLINE 0x5000c5000b9f5965 1 7 70007 PRIMARY ONLINE The second command shows the location (controller-wise) and the part number of the disk: sasmgr get_info -D /dev/sasd0 -q lun=all -q lun_locate Output: RAID VOL ID is 7 : /dev/rdsk/c0t2d0 0/4/1/0.0.0.2.0 Physical disks in volume are : 1 1 OFF HP EG0300FCSPH HPD0 1 7 OFF HP DG072BB975 HPDC RAID VOL ID is 2 : /dev/rdsk/c0t3d0 0/4/1/0.0.0.3.0 Physical disks in volume are : 1 8 OFF HP DG146BABCF HPD5 1 2 OFF HP DG146ABAB4 HPD5 In my case disk 1,2 failed: 0x5000c50003aeb459 1 2 140014 SECONDARY FAILED [...] 1 2 OFF HP DG146ABAB4 HPD5 With this part number we can order a new disk. `dmesg` was also spitting out warning about this disk issue: SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 SAS driver at 0/4/1/0 (/dev/sasd0) : TM (0x00000002) to SAS address 0x03c5c0600358833e (dev_t 0x03000006) failed with CDB status 0x00000400 LVM: VG 64 0x010000: Lost quorum.
