Hi all,
I have a wiered phenomenon on a NBU 7.5.0.3. media server.
i have connected 20 drives via FC to this host.
Two rives are missing, because they are faulty and have to be changed, those are turned off, so it should not show up at the host at all.
When I do a rescan in windows device manager, everything is fine, there a 18 drives.
When I now do a scan with netbackup!
PS C:\Program Files\Veritas\Volmgr\bin> ./scan | select-string "Device I" | sort
Device Identifier: "IBM ULTRIUM-TD5 F002547001"
Device Identifier: "IBM ULTRIUM-TD5 F002547007"
Device Identifier: "IBM ULTRIUM-TD5 F00254700D"
Device Identifier: "IBM ULTRIUM-TD5 F002547013"
Device Identifier: "IBM ULTRIUM-TD5 F002547019"
Device Identifier: "IBM ULTRIUM-TD5 F002547019"
Device Identifier: "IBM ULTRIUM-TD5 F00254701F"
Device Identifier: "IBM ULTRIUM-TD5 F002547025"
Device Identifier: "IBM ULTRIUM-TD5 F00254702B"
Device Identifier: "IBM ULTRIUM-TD5 F002547031"
Device Identifier: "IBM ULTRIUM-TD5 F002547037"
Device Identifier: "IBM ULTRIUM-TD5 F002566001"
Device Identifier: "IBM ULTRIUM-TD5 F002566007"
Device Identifier: "IBM ULTRIUM-TD5 F002566019"
Device Identifier: "IBM ULTRIUM-TD5 F00256601F"
Device Identifier: "IBM ULTRIUM-TD5 F002566025"
Device Identifier: "IBM ULTRIUM-TD5 F00256602B"
Device Identifier: "IBM ULTRIUM-TD5 F00256602B"
Device Identifier: "IBM ULTRIUM-TD5 F002566031"
Device Identifier: "IBM ULTRIUM-TD5 F002566037"
Don't count the, these are 20!
As you can see 2 serial numbers show up twice!
Here are the details from 1 of those candidates:
Device Name : "Tape3"
Passthru Name: "Tape3"
Volume Header: ""
Port: 2; Bus: 0; Target: 11; LUN: 0
Inquiry : "IBM ULTRIUM-TD5 D2A6"
Vendor ID : "IBM "
Product ID : "ULTRIUM-TD5 "
Product Rev: "D2A6"
Serial Number: "F002547019"
WWN : ""
WWN Id Type : 0
Device Identifier: "IBM ULTRIUM-TD5 F002547019"
Device Type : SDT_TAPE
NetBackup Drive Type: 10
Removable : Yes
Device Supports: SCSI-6
Flags : 0x0
Reason: 0x0
Device Name : "Tape3"
Passthru Name: "Tape3"
Volume Header: ""
Port: 2; Bus: 0; Target: 4; LUN: 0
Inquiry : "IBM ULTRIUM-TD5 D2A6"
Vendor ID : "IBM "
Product ID : "ULTRIUM-TD5 "
Product Rev: "D2A6"
Serial Number: "F002547019"
WWN : ""
WWN Id Type : 0
Device Identifier: "IBM ULTRIUM-TD5 F002547019"
Device Type : SDT_TAPE
NetBackup Drive Type: 10
Removable : Yes
Device Supports: SCSI-6
Flags : 0x0
Reason: 0x0
What is this?
Port 2/0/11 is the working one, Port2/0/4 is dead, I can see this directly at the HBA!
Why does Netbackup think that the dead drive has the same serial than another drive in the same library?
During the last night I saw lots of these in the windows appl log:
serial number check failed on Drive002 (device 4, SCSI coordinates {2,0,4,0}, \\.\Tape3), drive serial number is F002547019, database serial number is F00256600D, DOWN'ing it
These are IBM LTO5 drives, driver is installed non-exclusive.
best regards
