In certain cases, Promise VTrak RAID drives that belong to an array may go offline. One such case occurs when a RAID head is booted before its corresponding expansion chassis. In such situations, the drives that compose an array may be Offline, which results in the physical drives status being reported as "Dead" and the Logical Drive status reported as Offline in the web administration interface. The arrays drives light may be red.
To resolve this issue, an administrator should manually bring the drives online. To do so, follow these steps:
Shutdown and Boot the RAID Head and expansion chassis in the correct order.
Establish a Telnet connection to the RAID head over port 2300. To do so, open Terminal (in /Applications/Utilities) and issue the following command:
telnet IP_Address 2300
Replace IP_Address with the IP Address assigned to the RAID heads Ethernet port. If you are not certain what IP Address is assigned to the Promise RAID, refer to the Product Manual.
3. Authenticate when prompted. If you are not certain what administrator name and password is assigned to the Promise RAID, refer to the Product Manual.
4. Issue the following command:
phydrv
This command will produce a list of drives and their status. Drives with red lights may be reported with status "Dead".
In this example, Drives 17 and 18 are reported as "Dead":
=============================================================
PdId Model Type CfgCapacity Location OpStatus ConfigStatus
=============================================================
16 ST3750640NS SATA 698.49GB Encl1 Slot16 OK Array0 SeqNo4
17 ST3750640NS SATA 698.49GB Encl2 Slot1 Dead Array0 SeqNo5
18 ST3750640NS SATA 698.49GB Encl2 Slot2 Dead Array0 SeqNo6
5. For each of the drives with the OpStatus, Dead, issue the following command:
phydrv -a online -p PdId
Replace PdId with the PdId number which corresponds to the number farthest to the left in the previous steps output. For example, to bring Drive 17 online, the following command would be issued: phydrv -a online -p 17
Once this command has been executed for each drive that is reported Dead, issue the following command again to review the status of the drives:
phydrv
Notice that the drives that were reported offline are now reported as Forced Online. For example:
=============================================================
PdId Model Type CfgCapacity Location OpStatus ConfigStatus
=============================================================
16 ST3750640NS SATA 698.49GB Encl1 Slot16 OK Array0 SeqNo4
17 ST3750640NS SATA 698.49GB Encl2 Slot1 Forced Onl Array0 SeqNo5
18 ST3750640NS SATA 698.49GB Encl2 Slot2 Forced Onl Array0 SeqNo6
If a drives OpStatus remains Dead, contact Promise Support.
