更換storage ,可以保留device name 嗎

[watermelonyu]

我現在的storage 是MA8000

device name是

$1$DGA101

$1$DGA102

我打算更換成EVA4000

請問我新的device name 可以改成跟MA8000一樣嗎

因為原有硬碟上面有裝oracle ,如果device name 跟舊的不一樣,要重新安裝Oracle

If MA8000 and EVA4000 will be used together during data migration to EVA4000, then every virtual disks presented to OpenVMS must be with different unit no.



For your situation, I'll do the following steps (assume that the disks on EVA4000 presented are $1$DGA201, $1$DGA201),



1. shutdown Oracle

2. duplicate($backup/image) $1$DGA101 to $1$DGA201, duplicate $1$DGA102 to $1$DGA202

3. shutdown VMS

4. disconnect MA8000 from VMS (or unpresent disks on MA8000 to VMS)

5. On EVA4000, change "OS UNIT ID" (201 -> 101, 202 -> 102)

6. reboot VMS



If you can't shutdown VMS in step 3, in step 6 you can
