EMS not seeing all disks on system - how to configure

[Randy Hagedorn]

Hi,

I am trying to configure some missing disks from EMS. monconfig shows that the following disks are being monitored:

/storage/events/disks/default/10_4_4.6.0
/storage/events/disks/default/10_4_12.0.0
/storage/events/disks/default/10_4_12.4.0
/storage/events/disks/default/10_4_12.6.0
/storage/events/disks/default/10_0.5.0
/storage/events/disks/default/10_0.6.0

An ioscan -fn -C disk shows more disks on the system, some of which are not listed in monconfig.

Disks installed on system:

disk 0 10/0.5.0 sdisk CLAIMED DEVICE SEAGATE ST15150W
disk 1 10/0.6.0 sdisk CLAIMED DEVICE SEAGATE ST15150W
disk 2 10/4/4.0.0 disc3 CLAIMED DEVICE SEAGATE ST336704LC
disk 3 10/4/4.1.0 disc3 CLAIMED DEVICE SEAGATE ST336704LC
disk 4 10/4/4.4.0 disc3 CLAIMED DEVICE SEAGATE ST318437LC
disk 5 10/4/4.5.0 disc3 CLAIMED DEVICE SEAGATE ST318437LC

disk 6 10/4/12.0.0 disc3 CLAIMED DEVICE SEAGATE ST318436LC
disk 7 10/4/12.1.0 disc3 CLAIMED DEVICE SEAGATE ST336704LC
disk 8 10/4/12.4.0 disc3 CLAIMED DEVICE SEAGATE ST318436LC
disk 9 10/4/12.5.0 disc3 CLAIMED DEVICE SEAGATE ST318437LC
disk 12 10/4/12.6.0 disc3 CLAIMED DEVICE SEAGATE ST19171N
disk 10 10/12/5.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM XM-5401

I am wondering why EMS is not seeing all disks such as 10/4/4.0.0. Are only certain disk drive models able to be utilized with EMS?

Thanks,
Randy

Shalom Randy,

I've never seen this before.

Perhaps they need to be configured and part of a volume group to be monitored.

Are they all part of a vg?

Hi

Have you try to add others disks by Sam
->ressources management -> EMS ->add monitoring requests

As I look at my thread submission, I noticed that the drives not listed are models ST336704LC and ST318437LC. Are these possibly not able to communicate with EMS?

Thanks,
Randy

Hi Randy,
Are the disks that EMS is not monitoring genuine HP-supplied drives, or from a third-party? EMS only monitors drives with HP firmware installed. You can check the level by running the STM Info tool on the disks and looking at the output.

Also, do you have a current version of the OnlineDiags installed?

With response from Andrew, I investigated the firmware level of the missing disks with stm and they do not begin with the letters, 'HP'. So with that information, I am correlating that this is the reason these disks do not appear in monconfig. Now I need to find how to update the firmware to an HP level with my 3rd party vendor.

Thanks all,
Randy

You should get the same answer from your disk vendor, but I believe the HP firmware is only intended to be installed on HP supplied disks, not third-party drives. The HP firmware has not been tested except with the drives that HP supplies.

Again, because only HP supplied drives have been tested, the EMS HW Monitor, disk_em, only monitors drives with HP firmware (as a way of recognising HP supported hardware).
