Re: replacing a bad disk on SC10 array / FC60 (help plz)
Both drives are on the same channel. Are these two disks in the same enclosure with the BCC that is marked as "Unknown"? Are there any other drives in this enclosure on this same bus?. It could be that the "bad" BCC is causing the disks to report as bad/unknown. One of them is being spared, but the other (4:0) is not, yet the LUN it belongs to is still marked as OPTIMAL. Strange. Id work to get the BCC and the array controller working before messing with the disk modules at this time.

Re: replacing a bad disk on SC10 array / FC60 (help plz)
Hello Bob,
how can i find if these 2 disks (4:0 and 4:1) are in the same enclosure with the BCC controller that is marked as "unknown"? These 2 disks are located on the SC10 disks array (bay 2) however the BCC controller isn't meant to be located in the controller B enclosure? Note that both controllers A and B are meant to be configured for redundancy (connected to 3x SC10 disks arrays and 2 servers / server 1 : Application server and server 2: Database server).
So, in your opinion, first i should replace the BCC & controller ?
Thanks in advance

According to the amdsp output the bad controller is disk enclosure "2", but thumbwheel setting of 1 is what is referenced:
Firmware Revision = HP04 Information for Disk System 2 (USSD00098870), Controller A: SCSI Channel = 3 Thumbwheel Setting = 1 Controller Status = GOOD Vendor ID = HP Product ID = A5294A BCC Serial Number = USSD00098870 Firmware Revision = HP04 Information for Disk System 2 (USSD00098870), Controller -1: SCSI Channel = 0 Thumbwheel Setting = -1 Controller Status = UNKNOWN Vendor ID = NO_VENDOR Product ID = NO_MODEL BCC Serial Number = NO_SER_NUM Firmware Revision = NO_FWREV
From your first amdsp attachment you can see that disk 4:0 is in enclosure 1, slot 1 and disk 4:1 is in enclosure 1, slot 3. Both of these disks are affected by the faulted BCC "B". Replace that to get your disks back (hopefully).
> however the BCC controller isn't meant to be located in the controller B enclosure?
Not sure what you mean, but array controllers and BCC (bus control card) are different. There is an A and B for each.
> So, in your opinion, first i should replace the BCC & controller ?
Replace the BCC to hopefully get all of your drives in good order. Then focus on the array controller as previously discussed.
Thats my suggestion anyways!!

Re: replacing a bad disk on SC10 array / FC60 (help plz)
Hello,
still getting issues on this topic, we replaced both BCCs on disk system2 and proceed by replacing the controller with no results. We proceeded by backing up all data and syswiped the array and now when trying to create a LUN on controller B we received the following output:
> amcfg -force -L B:1 -d 2:0,4:0,6:0 -r 5 -s 16 Array1
Error in command execution, "RMT_AM60ERRORSTATUS_MSG"
AM60ERR : ERR_COMMAND_FAILED
AM60ERR QUAL : CREATE_LUN
MODULE_CODE_ID : SUBSYSTEM
COMMAND STATE : A SCSI error occurred
ERROR NUMBER : 2
Sense Key = 0x05: "ILLEGAL REQUEST"
Additional Sense Code = 0x91
Additional Sense Code Qual = 0x03
Decoded SCSI Sense:
Illegal Operation for Current Disk State
amcfg: Error in command execution
isnt syswipe intended to delete all disks data and config?
Any help is much appreciated

It looks like there is still a hardware issue somewhere.
Does amdsp -a report any improvements since the controller replacements you referenced?

No improvements even after replacing the controller.
These FC60 are too weird, i troubleshooted everything (scsi cables, ports.......)
then by itself after some time it showed no problems and everything went OK.
However nobody knows what does it happen. Too Weird !

This is probably the line that says it all;
> These FC60 are too weird,
Very true!
