\nOma t\u00f6\u00f6s kogen tihti j\u00e4rjepidevat muret teabe puudumise \u00fcle infrastruktuuri osas ning suureneva serverite arvu korral muutub see t\u00f5eliseks piinaks. Isegi kui ma t\u00f6\u00f6tasin v\u00e4ikestes organisatsioonides, soovis ma alati teada, mis kus asub, kuhu on midagi \u00fchendatud, kes vastutab millise riistvara v\u00f5i teenuse eest ning mis k\u00f5ige t\u00e4htsam - fikseerida k\u00f5ik muudatused selles osas. Uude kohta tulles ja silmitsi seistes m\u00f5ne probleemiga, kulub tohutult aega just selle teabe leidmiseks. J\u00e4rgnevalt r\u00e4\u00e4gin, millega ma RuVDS-is silmitsi seisma pidin ja kuidas ma lahendasin artikli pealkirjas v\u00e4ljendatud probleemi.
\n<\/a><\/noindex><\/p>\n

Eellugu<\/h2>\n

\nOlles ettev\u00f5tte tasemel administraator, oli mul v\u00e4he kogemusi andmekeskustes, kuid n\u00e4gin korra silmanurgast RackTables'i. Seal oli selgelt esitatud kapp koos k\u00f5igi serverite, UPS-ide, l\u00fclitite ja nende vaheliste \u00fchendustega. RuVDS-is sellist s\u00fcsteemi ei olnud, vaid ainult Exceli\/paberifailid serverite, nende osade, rackide numbrite jne kohta. Sellise l\u00e4henemisega on v\u00e4ga raske j\u00e4lgida muudatusi ja t\u00f6\u00f6tada v\u00e4ikeste komponentidega. Ning peamine ja tihti vahetatav tarvik serverite puhul on kettad. V\u00e4ga oluline on hoida ajakohast teavet ketaste oleku ja nende strateegilise varu kohta. Kui ketas kaob RAID-massiivist ja ei ole kiiret asendust, v\u00f5ib see l\u00f5ppkokkuv\u00f5ttes p\u00f5hjustada katastroofilisi tagaj\u00e4rgi. Seet\u00f5ttu on meil h\u00e4dasti vaja s\u00fcsteemi, mis j\u00e4lgib ketaste asukohta ja nende seisundit, et m\u00f5ista, millest v\u00f5ib puudust tunda ja milliseid mudeleid tuleb soetada.<\/p>\n

Abiks tuli GLPI, avatud l\u00e4htekoodiga toode, mis on loodud IT-osakondade t\u00f6\u00f6 parandamiseks ja viimiseks ITIL-i ideaalidesse. Lisaks seadmete inventuurimisele ja rackide haldamisele on seal teadmusbaas, teeninduslaud, dokumentide haldamine ja palju muud. GLPI-l on palju pluginaid, sealhulgas FusionInventory ja OCS Inventory, mis v\u00f5imaldavad automaatselt koguda teavet arvutite ja teiste seadmete kohta agentide ja SNMP kaudu. GLPI ja pluginate paigaldamise kohta saate rohkem lugeda teistes artiklites, k\u00f5ige parem on - ametlikust dokumentatsioonist<\/a><\/noindex>. Saame selle paigaldada meie hostingus juba valmis \u0161abloonile LAMP<\/a><\/noindex>.<\/p>\n

Kuid p\u00e4rast agendi deployimist avame GLPI-s arvuti komponendid ja n\u00e4eme sellist pilti:<\/p>\n

\"LSI
\nProbleem on selles, et \u00fckski pistikprogramm ei saa LSI RAID-massiivide f\u00fc\u00fcsiliste ketaste teavet n\u00e4ha. Olen n\u00e4inud, kuidas see k\u00fcsimus Zabbixis PowerShelli skripti abil lahendatakse. lsi-raid.ps1<\/a><\/noindex> otsustasin kirjutada sarnase, et edastada teavet GLPI-le.
\nMassiivi ketaste teavet saab tootja kontrolleri utiliitide abil, LSI puhul on see StorCLI. Sellega saab andmed JSON-formaadis, t\u00f5lgendada ja saata GLPI API-sse. Ketast seome arvutitega, mille on juba loonud FusionInventory. Skripti korduva k\u00e4ivitamise korral uuendab see ketaste andmeid ja lisab uusi. Ise skript Send-RAIDtoGLPI.ps1 asub siin GitHubis<\/a><\/noindex>. J\u00e4tkan edasise kasutamise \u00f5petamisega.<\/p>\n

Mida on vaja<\/h2>\n

<\/p>\n

    \n
  1. GLPI<\/a><\/noindex> versioon 9.5.1 (testimiseks kasutatakse seda versiooni)<\/li>\n
  2. Pistikprogramm FusionInventory<\/a><\/noindex> ja agent Windowsi jaoks<\/li>\n
  3. Windows 2012 R2 (ja uuem) hostimisoperatsioonis\u00fcsteemina v\u00f5i management-VM, millel on kontroller \u00fchendatud, PowerShelli versioon 4 v\u00f5i uuem<\/li>\n
  4. Installeeritud MegaRAID draiver<\/li>\n
  5. PowerShelli moodul \u2014 PSGLPI <\/a><\/noindex><\/li>\n
  6. GLPIs peab olema Admini profiiliga konto liidese kaudu autentimiseks, genereeritud UserToken ja AppToken<\/li>\n<\/ol>\n

    \nOluline punkt. GLPIs on mingil p\u00f5hjusel 2 erinevat moodulit ketaste jaoks, kuid pole omadust \u201ekandja t\u00fc\u00fcp\u201d. Seet\u00f5ttu otsustasin ketaste omaduste HDD ja SSD registreerimiseks kasutada rippmen\u00fc\u00fcd \u201eKetta mudelid\u201d (front\/devicemodel.php?itemtype=DeviceHardDriveModel). Skripti jaoks on vajalik, et GLPIs oleks need v\u00e4\u00e4rtused olemas, vastasel juhul ei saa ta ketta mudeli andmeid salvestada. Seet\u00f5ttu tuleb esmalt sisestada HDD ja seej\u00e4rel SSD t\u00fchjasse nimekirja, et nende elementide ID-d oleksid andmebaasis 1 ja 2. Kui on teisi, asendage see rida skriptis Send-RAIDtoGLPI.ps1 p\u00e4rast HDD ja SSD vastavate ID-idega 1 ja 2. <\/p>\n

    deviceharddrivemodels_id = switch ($MediaType) { \"HDD\" { \"1\" }; \"SSD\" { \"2\" }; default { \"\" } }<\/code><\/pre>\n
    \nKui te ei soovi sellega vaeva n\u00e4ha v\u00f5i kasutate seda rippmen\u00fc\u00fcd muul viisil, v\u00f5ite selle rea skriptist lihtsalt kustutada. <\/p>\n
    Peate ka lisama ketaste staatuseid \u201eElemendi staatused\u201d (front\/state.php). Olen lisanud staatuse \u201eMediaError\u201d (kui on olnud v\u00e4hemalt \u00fcks ketta ligip\u00e4\u00e4su t\u00f5rge) ja \u201eOK\u201d, ridu skriptis, kus edastatakse nende ID-d, \u201e2\u201d \u201eOK\u201d jaoks ja \u201e1\u201d \u201eMediaError\u201d jaoks:<\/p>\n
    states_id = switch ($MediaError) { 0 { \"2\" }; { $_ -gt 0 } { \"1\" } }<\/code><\/pre>\n
    \nNeed staatuseid on mugavuse huvides, kui need omadused pole vajalikud, v\u00f5ite ka selle rea t\u00e4ielikult kustutada.<\/p>\n
    \u00c4rge unustage skriptis oma muutujaid m\u00e4rkida. $GlpiCreds peab sisaldama GLPI API serveri URL-i, UserToken'i ja AppToken'i.<\/p>\n
    Mis on skriptis<\/h2>\n
    \nSkripti suur JSON-parsimine ja pikk if-ute sisemine struktuur muudavad selle lugemise keerukaks, seet\u00f5ttu kirjeldan selle loogikat siin.<\/p>\n
    Esimese k\u00e4ivitamise ajal l\u00e4bib skript k\u00f5ik kontrollerid ja otsib GLPI andmebaasist kettaid seerianumbrite p\u00f5hjal. Kui seerianumbrit ei leita, otsitakse mudelit. Kui ka mudelit ei leita, lisatakse uue ketta mudel GLPI-sse ja ketas kantakse andmebaasi.<\/p>\n
    Iga j\u00e4rgmise k\u00e4ivitusega \u00fcritab skript avastada uusi kettaid, kuid puuduvate eemaldamine ei ole tema v\u00f5imekuses, seega tuleb see teha k\u00e4sitsi.<\/p>\n
    N\u00e4idis rakendusest<\/h2>\n
    \nSkripti reposse on lisatud skript Deploy-Send-RAIDtoGLPI.ps1, mis t\u00f5mbab vajalikud failid ZIP-arhivina meie GLPI serverist ja paigaldab need igale hostile.<\/p>\n
    Failide kopeerimise j\u00e4rel installib skript FusionInventory agenti, mis seadistatakse igap\u00e4evaseks \u00fclesandeks, ja loob sarnase \u00fclesande meie skripti jaoks. P\u00e4rast edukat rakendamist saame l\u00f5puks n\u00e4ha kettaid GLPI-s arvuti 'Komponendid' jaos.<\/p>\n
    Tulemus<\/h2>\n
    \nN\u00fc\u00fcd, kui siseneme GLPI-sse ja valime men\u00fc\u00fcst 'Seaded' -> 'Komponendid' -> 'K\u00f5vakettad', saame kl\u00f5psata ketaste mudelitel ja n\u00e4ha nende arvu, et m\u00f5ista, mida peame ostma.<\/p>\n
