A seguito di un blackout l’infrastruttura di backup di un cliente (composta da tsm 6.2 e libreria ts3310 con tre drive via FC) ha incominciato da dare degli errori (considerate che tutti e 3 i componenti HW si sono riavviati Server linux, libreria e switch in fibra) :

ANR8413E UNABLE OPEN DRIVE /dev/IBMtape2 error number 12

Dopo essermi salvato la configurazione dei drive  in un file di testo:

tsm: OMER>query path f=d

Ho ridefinito i due path che in questo caso mi davano errori i path erano del DRIVE0 e DRIVE2:

mi ero accorto che erano questi i drive perche facendo un update con le correnti configurazioni mi compariva un messaggio di errore:

tsm: OMER>update path OMER DRIVE2 srctype=SERVER autodetect=yes desttype=drive library=TS3310_MO device=/dev/IBMtape0
ANR8419E UPDATE PATH: The drive or element conflicts with an existing drive in library TS3310_MO.
ANS8001I Return code 15.

Adesso sembra andare tutto….
