Dell PERC H700 na Linuxu: postup výměny disku a bash skript pro stav řadiče i baterie

Pokud nechcete ztrácet čas hledáním nějakého skriptu, který by vám vypsal všechny diagnostické informace o vašem řadiči Dell Perc H700, tak jste právě našli.
Skript si můžete uložit třeba do /root/fullstatus.sh
chmod 700 /root/fullstatus.sh
pokud se nacházíte v rootovi tak ./fullstatus.sh
A obsah by mohl být zhruba následující:

#!/bin/bash

Co předcházelo nasazení HDD ve slotu 2 do pole?

Základní postup (s MegaCli)

1. Jak nalézt ID disku /opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | less
   U každého disku je uvedeno Enclosure Device ID a Slot Number.
   Nahrazený disk má v mém případě Slot Number: 2. Ujistíme se proto, že sedí Enclosure Device ID.
2. Přidání disku do pole (force rebuild)
   Pokud je VD (RAID pole) degradované a slot 2 je jeho člen (pozor, některé stroje mohou mít víc řadičů a raidů), ale disk je nový, můžeme zadat příkaz:
   (tím disk dáme do stavu Dobrý = Good)
   [E:S] namená [EnclosureID:Slot number], musíte nahradit ID, která zjistíte z předchozího příkazu
   /opt/MegaRAID/MegaCli/MegaCli64 -PDMakeGood -PhysDrv [E:S] -a0

/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -Start -PhysDrv [E:S] -a0
   
   kde [E:S] znamená [EnclosureID:SlotID], např. v mém případě [32:2].
   Jinak lze disk nastavit jako hotspare:
   /opt/MegaRAID/MegaCli/MegaCli64 -HotSpare -PhysDrv [E:S] -a0
   a řadič ho použije pro rebuild sám.
3. Taky lze sledovat stav rebuildu příkazem:
   /opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [E:S] -a0
   (funkční příklad:
   /opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [32:2] -a0
   Rebuild Progress on Device at Enclosure 32, Slot 2 Completed 2% in 32 Minutes.
   Exit Code: 0x00 )
   nebo stav celého pole příkazem:
   /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -a0

Command historie v mém případě

Pokud budete řešit totéž u vašeho pole nahraďte [32:2] za číslo Enclosure device ID a Slot Number vašeho vyměněného disku v poli.
