The issue is an known issue and the errors don't affect the data integrity, future firmware will fix the issue. We discovered the same issues today on our MSA2324fc. We consulted the HP Storage Engineer who setup the SAN and he gave us this answer:
HP StorageWorks 2000 G2 Modular Smart Array (MSA) - Products Generating "Disk channel error" Events when MSA70 Enclosures Used as Expansion JBODs
HP StorageWorks 2000 G2 Modular Smart Array (MSA) products with firmware code M110R21 and M110R20 connected with MSA70 Drive enclosures generate the following event:
Disk channel error.
We observed the following events on MSA2000 G2 store.log , which are connected with MSA70 drive enclosures:
A359 2009-08-27 08:02:07 59 I A Disk channel error. (channel: 0, ID: 63, SN: SGA, enclosure: 2, slot: 32): Protocol Error CDB:1c0102015c00
A360 2009-08-27 10:41:59 59 I A Disk channel error. (channel: 0, ID: 34, SN: 3SE0M4H500009948PZR9, enclosure: 2, slot: 3): Protocol Error CDB:Rd 1ef98f00 0080
A361 2009-08-27 10:41:59 59 I A Disk channel error. (channel: 0, ID: 36, SN: 3SE0M2A100009948P8B5, enclosure: 2, slot: 5): Protocol Error CDB:Rd 1ef98f00 0080
A362 2009-08-27 10:41:59 59 I A Disk channel error. (channel: 0, ID: 38, SN: 3SE0M2ZC00009949U37X, enclosure: 2, slot: 7): Protocol Error CDB:Rd 1ef98f00 0080
Disk channel errors reported by drives on an MSA70.
When an MSA2000 G2 array is using MSA70s as expansion JBODs, disk channel errors might be reported. These errors do not affect data integrity and are being investigated for correction in a future update of firmware.
I know this is an old thread, but is there any update to this issue? I've begun seeing these warnings on my MSA2324i with MSA70 Expansions. Please let me know if there has been a firmware update to correct the issue.
It does not seem that there is a solution and all indications are that we should ignore this event.
I have a MSA2324i with a MSA70 enclosure. I have upgraded the firmware on the MSA2324i to the latest M114P01-01:
The MSA70's firmware was already to at the newest version.
Disk firmware upgrades end in error.
I continue to get the error:
Disk channel error (channel 0, ID 63, SN:SGA00201YO, enclosure 2 slot32): I/O timeout CDB: 1c0102015c00
I have also reconfigured the disks and volumes and get the same message even if there is no data or access or I/O on the MSA2324i and MSA70 enclosure.
