Post subject: | Adding used disks from a retiered T400 to another T400 |
Hi Guys, First time here so hopefully someone can help me out, We have 2 T400 both out of maintenance, and 1 has been decommissioned, we are trying use the disk on the decomm'd Array in the Running array, We preformed servicemag start 4 0 once it succeeded we took the disk out of the unused array and installed in the place of the failed disk, then servicemag start 4 0 and this completed, but only the originall good drives came online and the failed disk reports the following Code: T400INSERV01 cli% showpd -c 184 ------- Normal Chunklets -------- ---- Spare Chunklets ---- - Used - -------- Unused -------- - Used - ---- Unused ---- Id CagePos Type State Total OK Fail Free Uninit Unavail Fail OK Fail Free Uninit Fail 184 4:0:2? FC failed 1115 0 0 0 0 571 544 0 0 0 0 0 ----------------------------------------------------------------------------------------- 1 total 1115 0 0 0 0 571 544 0 0 0 0 0 T400INSERV01 cli% showpd -state 184 Id CagePos Type -State- ----------------------------------Detailed_State---------------------------------- 184 4:0:2? FC failed vacated,missing,not_available_for_allocations,invalid_media,failed_hardware,spinup ----------------------------------------------------------------------------------------------------------- 1 total How can I force the disk to come on-line and be accepted by the array, remembering that this disk was once used in another array and was never dismissed from that array. Thanks. |

Having an high end array without support is just... s t u p i d. |

I'll take this comment with a pinch of salt, and educate you a bit, The unit is going on for 5 years old, we are using it for non-critical dev & test, it was replaced with an all flash array, but rather than through a good piece and equipment worth over $1mil away we re-purposed it for POC, DEV&TEST, and RND. Now HP will not work on the unit unless it has an active support contract and as the unit is perfect except for a few failed disks, why not maintain it ourselves and ask on this forum if anyone can assist, after all if everyone had support why would we even bother with forums likes this ? |

I now how old are T series. I started in august 2008 on 2 T400. On these old arrays disks replacement is done by support not by end customers as it is done on 7xx0. Thanks for the education I'm not in charge of support in my company but the few failed disks i paid attention to never had so many errors... One thing you could do: insert old mag in your active array, do admithw, check if the disk are in a good state, remove the spare from them (removespare -f pdid:a) and dismiss the pd (dismisspd pdid). That way you will be sure the disks you use are valids. For the trouble you are facing i got no idea. You can ever try this : showpd -i controlport chmederr set -1 pdwwn controlport chmederr set -2 pdwwn controlport chmederr unset -2 pdwwn controlport chmederr unset -1 pdwwn controlport clearerr pdwwn That will force the reset of some errors... But... I did not know forums was made to replace failed disks. |

Ok so it seems the replacement disks were actually accepted, it's just the old disks were not removed and are still reproting in the system Code: T400INSERV01 cli% showpd -p -mg 0 -cg 4 ---Size(MB)--- ----Ports---- Id CagePos Type RPM State Total Free A B Cap(GB) 112 4:0:0 FC 15 normal 285440 114688 2:2:1* 3:2:1 300 113 4:0:1?

running these commands is harmfull... If the pds still have data (spare, etc...) you ll know it. |

Turns out running those commands was the right thing to do, From this link http://ftp1.osiatis.com:8081/doc.do;jsessionid=1og68mt5p5onj?docId=p_dvd12%2Femr_na-c02660861.pdf Code: For the servicemag start command only, instead of using the <cage_ID> <magazine> specifiers, the disk(s) to be serviced can be specified using the -pdid option and servicemag resume will automatically dismiss the specified disk(s) when it completes. However, if servicemag unmark <cage> <mag> is run before the servicemag resume command, the disk(s) specified with the –pdid option, will not be automatically dismissed. X Workaround - When the servicemag resume <cage> <mag> has successfully completed, check using the showpd command if the disks specified with the -pdid option are still in the system. If so, you will need to dismiss those disks manually by running dismisspd <pdid>. We didn't use the pdid instead we did the cage and mag, and this is way the old disks remained registered even though they had been successfully replaced. |
