I’d like to know what physical disk drives are attached to an IRIX system, and the capacity (or at least geometry) of each disk. I can get the former through hinv, but that doesn’t include capacity/geometry/etc. and my attempts to find this information have so far only yielded frustration. Does anyone know the proper incantation? … Read more
We have a powerbi embedded capacity that we pause at night and we resume again early in the morning. We have been doing this for the last month and we have had no problem, but last two days we get errors when the capacity try to resume. When this happens we make a resume attempt … Read more

Hard drives with equal capacity specs are not really equal in size, e.g. I have two 4TB disks with the following capacities: Disk 1: 4,000,752,599,040 bytes Disk 2: 4,000,786,153,472 bytes Afaik a 4 TB drive has at least 4,000,000,000,000 bytes. I read that one should make a RAID partition 100MB smaller than the disks full … Read more
Two 4TB drives are connected to a Promise SuperTrak EX8350 controller with the intention of setting-up a RAID 1 array. Before attempting to create any logical drives, the capacities of both drives show up as 2199.02 GB (in the Promise Array Manager utility). Is it possible to configure/update the Promise SuperTrak EX8350 so as to … Read more
